Galliformes and other animals for South America (ïðîäîëæåíèå)
JOrnitho: Hello! I'm back with ideas for some new species for South America. I found in my computer an archive with some ideas for fauna and flora that I had some time ago and decided to show there to ask your opinion about them. The first is about a descendant of the domestic chicken. [more]Copper jacumitan (Jacumita cuprinus) During the Holocene, the man introduced many species in other continents. The jacumitan is a descendant of domestic chicken (Gallus gallus domesticus) that are introduced in South America. It replaced the birds in the family Cracidae, which are extinct in the Neocene, in some areas. In a matter of fact, the name jacumitan is the junction of the words jacu, the popular name in Brazil for guans of the Genus Penelope, and the tupi word mitã (mitan) that means new, this way the name means “new guan”. The copper jacumitan is the type species of this genus and lives in the savannas and woodlands of Central South America. The copper jacumitan is sexually dysmorphic. The male measure 190 cm, due to the long tail, it has a bright coppery brown upperbody plumage and reddish-brown feathers below. They also have metallic dark green feathers on the tail and wings. Only males have a bright red naked skin on the face, with two wattles that conceal the sides of its head. This characteristic is shared by all males of the genus Jacumita. The males of the genus also have crests formed by white feathers with black tips. During courtship and panic moments, they rise the crests. The females have 75 cm of length and are cryptic brown and adapted to camouflage, its naked skin on the face is pale pink and don’t have flesh wattles. The young males are similar to the females until they reach 9 weeks, at this time the wattle begin to develop. Both sexes have long orange colored legs and grey beak. The males have spurs that they use in fights for dominance. The neck is long and slim. Copper jacumitans can fly, but prefer to run from the predators flying only as last resort. These birds are omnivorous and feed on insects, seeds, and fruits. Its forage for food by scratching the ground, usually near herbivores this way there is other animals observing for the presence of predators. Often the male sits on a high perch, to serve as a lookout for his group. He sounds an alarm call if predators are nearby. At night it will sleep perched on branches. Copper jacumitans are polygamous; the male will have a harem with 5 to 12 females and will guards the area where his females are nesting, and attack other males that enter his territory. To initiate courting, the males will dance in a circle around or near a female, raising their crests and lowering the wing which is closest to the hen. Then, he will vocalize and when she responds to his call, the male will mount her and proceed with the mating. The females make their nest in the ground, laying 6 to 14 red eggs which are incubated for 22 days. Chicks are precocious, leaving the nest shortly they are born. They fledge in about 4 to 5 weeks, and at 13 weeks old are chased out of the group by their mother, at which point the young males start to form a harem and the females join an existing one. Sexual maturity is reached at 6 months and the lifespan of this species is of 13 years, however is common for males to die early due to predation. Other species in the genus Jacumita are: Golden jacumitan (Jacumita aurea) Living in the forests of the Atlantic coast of South America, the males of this species has 200 cm of length, from beak to tail, while the females have 83 cm. The plumage of the male have a bright golden-yellow plumage in the upperparts, being scarlet in the chest and belly. They have dark metallic green wing feathers and tail while the female is cryptic brown. Red jacumitan (Jacumita amazonica) Living in the "terra firme" forests of the Amazon , the males of this species has 185 cm of length, from beak to tail, while females have 70 cm. The plumage of male is bright orange-red in the upperparts, while their chest and belly is yellow. The males also have dark metallic blue wing feathers and tail while the female is cryptic brown. Andean jacumitan (Jacumita andina) Living in the highland forests in the slopes of the Andes, the males of this species has 170 cm of length, from beak to tail, while females have 68 cm. The plumage of the males is white in the upperparts and yellowish-red in the belly and chest. The males also have dark metallic blue wing feathers and tail while the female is cryptic brown. This other one is about a descendant of the californian quail: Common austral grouse (Tetraoinus australis) During the Holocene, the man introduced many exotic species different habitats, the ancestor of the austral grouse was one of these species. Their ancestor was not a true grouse, but the Californian quail, due to evolutionary convergence they acquired characteristics similar to the true grouses of North America. Living in the forests of Southern South America, the male austral grouse are 55 cm long and the female have 44 cm of length. The male have a dark grey body plumage, black-and-white bridled head pattern, black back and a greyish-blue belly. They have a curving crest or plume, made of six feathers that droops forward (long and black in males /short and brown in females) and long forked blackish tail with white undertail coverts. Females and immature birds are mainly greyish-brown with a light-brown belly. Both sexes have a black bill and relatively long grey legs. Their diet consists mainly of seeds and leaves, but they also eat some berries and insects. In some regions their main source of food are the seeds of trees of the Genus Araucaria. These birds are not elegant fliers, however they sleep perched in branches. Given a choice, they will normally escape on foot. During the courtship, the male austral grouse do displays on a lek, each male have a “personal space”. The males strut around their chose space, doing a display. The display consists of the male posturing himself with the head near the ground. Then, they start to move it from right to left showing their crests, simultaneously they raising the tail feathers, showing their withe undertail coverts. After that, they will raise their heads abruptly and whilst make a highly distinctive mating call. When another male invade the personal space of other, a fight happens, in this case the male will try to take of the crest of the rival, this way they will not be capable to display for the females. The female usually lays approximately 12 spotted eggs. The nest is a shallow scrape lined with vegetation on the ground. Incubation lasts from 21–25 days, usually performed by the female and rarely by the male. The chicks are precocial, leaving the nest with their parents within hours of hatching. The male stay with the female until the young leave, with 3 months. The young reach sexual maturity with 1 year, with this age the young males acquire the coloration of an adult male. Their lifespan is of 27 years. In the forests of Tierra del Fuego another species lives, the Black boreal grouse (Tetraoinus nigrus). Their main difference to the other species is that the males have an all-black plumage, with only a faint shade of blue in the chest and brown undertail coverts. The females are similar to that of the common austral grouse. The males have 52 cm and the females 41 cm.[/more] I also have in this archive some names for possible species that I never developed bayond some few facts. Maybe someone could help me make their descriptions.
ëÿãóøêà: JOrnitho Interesting!
JOrnitho: ìåäâåäü ïèøåò: Does the ancestor have this trait? The only owl I know to stash food is the Eurasian pygmy owl. Yes, they have. This video shows a Bubo virginianus hidding a raccoon in a hollowed tree.
Àâòîð: Is it a biologically reasonable behavior trait to store food in conditions of tropical climate? In temperate latitudes, in winter the stored prey is preserved due to cold weather. In tropical conditions, it will decompose soon due to high temperature. Is such behavior known among tropical birds?
JOrnitho: Àâòîð ïèøåò: Is it a biologically reasonable behavior trait to store food in conditions of tropical climate? In temperate latitudes, in winter the stored prey is preserved due to cold weather. In tropical conditions, it will decompose soon due to high temperature. Is such behavior known among tropical birds? It's possible. Jaguars and other predators when kill large prey will store the remnants under leaves or in secluded places. They'll come back to it as long as the meat is still consumable. I think that the owl, when killing large prey, could do that and return to eat for some time.
JOrnitho: I made two new species for South America Marsh chital (Axis palustris) Order: Artiodactyla Family: Cervidae Habitat: Wetlands and marshes that are formed by the Paraná River and its tributaries in South America, the largest population is located at the river's delta. During the Holocene, chital deer (Axis axis) was introduced in northern Argentina for hunting purposes. It didn’t take much time for some individuals to escape and spread to Uruguay and Southern Brazil. In these areas, they competed with the already endangered local species of deer (Ozotoceros and Blastocerus) and proved victorious while the others went extinct. In the Neocene they gave rise to the marsh chital, an inhabitant of the wetlands and marshes that are formed by the Paraná River and its tributaries in South America. This species is restricted and well adapted to these flooded areas, avoiding competition with deermaras in the plains and forests. The marsh chital is a moderate sized deer with visibly sexual dimorphism, with males being larger than females. Males reach up to 90 to 100 cm and females 65 to 75 cm at the shoulder, while the head-body length is 150 cm. While immature males weigh 30 to 75 kg, the lighter females weigh 25 to 45 kg. Mature stags can weigh up to 98 to 110 kg. The 20 cm long tail is marked by white tuft. When raised, this tail signals that there is a predator nearby. The antlers are present only on males, being lyre-shaped. They do not grow upwards, but tend to grow outwards and then inwards, with a smaller branch growing towards the front of the head. The brow tines are especially long and noticeable. Their body's upperparts are rufous, with horizontal white stripes being present at the sides. The abdomen, rump, throat, insides of legs and ears are light buff, while the tail is pure white. A conspicuous black stripe runs along the spine. The marsh chital has well-developed preorbital glands with stiff hairs. It also has well-developed metatarsal glands and pedal glands located in its hind legs. The preorbital glands, larger in males than in females, are frequently used to mark communication between different herds. They have very soft, insulated underfur, which is protected by an outer layer of long guard hairs. This traps a layer of air which keeps them dry and warm while they swim in the wetlands. They also have hooves adapted to move easily in the boggy ground. This species is a good swimmer, being able to dive and stay underwater for 3 minutes. This strategy is used to escape from terrestrial predators. The marsh chital feeds on a variety of water living plants, grasses, herbaceous plants, and shoots. Aquatic plants make most of their diet. It exhibits a bimodal activity pattern. They start grazing usually early in the morning, stopping when the temperature gets too high. In the evening, they start to forage when the temperature starts to drop and continue until sunset. After feeding it rests under thick and tall reeds and grasses. A gregarious animal, the marsh chital forms matriarchal herds comprising an adult female and her offspring of the previous and the present year, which may be associated with individuals of any age and either sex, male herds, and herds of juveniles and mothers. Small herds of 15 individuals are the most common, though aggregations of as many as 100 individuals can happen under favorable conditions such as during abundance of food in the rainy season. Groups are loose and disband frequently, save for the juvenile-mother herd. If an individual is stressed they will raise the tail as an alarm, revealing the white tuft. In case of a predator being seen, they will start to bark. The other deers will flee to nearest body of water, dive there and swim away. They don’t have a mating season, but most females become fertile during the dry season. Males will do displays with vocalization, tail rising and covering their antlers with aquatic plants. If two males show interest in the same female, the dispute is settled by clashing antlers. Gestation lasts approximately 271 days. The females give birth to one offspring per female, though occasionally twins are born. The infant deer are pale brown which becomes more adult-like when they reach sexual maturity with one year old. Marsh chital have a lifespan of 14 years. Gardener turkey (Meleagris hortulanus) Order: Galliformes Family: Meleagridae Habitat: Mountains and plateaus of South America, endemic to Araucaria forests in elevations of 500 to 1.600 metres. During the Holocene, the use of certain animals and plants in agriculture by humans resulted in them being spread to different continents. When humanity disappeared, some of these species became feral. Those that survived continued to evolve, with their descendants now living in the Neocene. The states of Southern Brazil once were important breeders of domestic turkeys that would be consumed during Christmas and New Year holidays. With the disappearance of humans, some of these birds went feral. However, they didn’t spread through much of South America and became limited to the areas of Araucaria forests, an ecoregion of the Atlantic Forest characterized by a montane subtropical moist forest. They became adapted to this habitat and in the Neocene gave rise to the gardener turkey, endemic to this ecoregion. The gardener turkey is sexually dimorphic, with females measuring 74 cm while the male is 110 cm long. The female weighs 1,100 g and the male 1,400 g. This species is slimmer than their ancestors, with a thin neck and small head. They are better fliers than their ancestors, with a wingspan of 160 cm. The plumage of the male is a mixture of bronze and green shades with iridescence. The wing feathers are white. Tail feathers are bluish-grey with an eye-shaped, bluish-purple spot near the end with a bright red tip. The female's plumage has several dull shades of brown and gray, with white wing feathers and a pale bronze tail. Mature males have a featherless, blueish-purple head and neck, with bright red throat and wattles. The head has fleshy bright red caruncles. The head and neck of the females is pale bluish-grey, lacking wattles and caruncles. The throat is pale pink. While omnivorous, gardener turkeys consume much more plant material, especially Araucaria pines. They also eat fruits, arthropods, small frogs, seeds and flower buds. Differently from their ancestors, gardener turkeys commonly forage in the trees, being agile and faster flyers. They sleep perched in tree branches during the night. They feed for several days in a row on trees that have a large quantity of fruit and usually follow predetermined routes to their preferred fruit trees. They also tend to return to the same fruit trees from year to year, which indicates that gardener turkeys are able to remember the ripening period and the location of these trees in the forest. They swallow the fruit whole, remove the pulp in the crop and regurgitate or defecate the seeds. It is important in the dispersal of several plant species, receing the name gardener because of it. Males are polygamous, mating with as many hens as they can. Nesting season starts in early spring. Male gardener turkeys display for females by puffing out their feathers, spreading out their feather tails, and dragging their wings. They have a vast number of vocalizations such as gobble, plain yelp, purr, cluck and excited yelp. Male forms leks, with a dominant one using gobbling and drumming sounds to assert dominance in the group and to attract females. When mating is finished, females search for nest sites. Nests are shallow dirt depressions engulfed with woody vegetation. Hens lay a clutch of 10–14 eggs, laying one white egg per day. The incubation lasts for at least 28 days. The poults are precocial, leaving the nest in about 12–24 hours. They stay with their mother for three months. Sexual maturity is reached within one year and their lifespan is 17 years old, but many perish early due to predation.
wovoka: JOrnitho, good animals.
ìåäâåäü: Interesting animals, but... When there is an abundance of pines, these birds will dig holes to hide and eat later. Seems more like a corvid behaviour than a turkey one. Galliforms are not that intelligent.
JOrnitho: ìåäâåäü ïèøåò: Seems more like a corvid behaviour than a turkey one. Galliforms are not that intelligent. Then, I'll change for them simply eating the pines. I think that the bird that could do that is a descendant of the azure jay (Cyanocorax caeruleus).
ìåäâåäü: Then, I'll change for them simply eating the pines. I think that the bird that could do that is a descendant of the azure jay (Cyanocorax caeruleus). That's a better solution!
JOrnitho: Some time ago, I learned that in the Brazilian state of Rondonia there are 5,000 water buffalos (Bubalus bubalis) living in the wild. They were introduced in the Guapore Valley for farming, but the project was abandoned and the animals became wild and there is no project to cull them. Besides these, there also thousands of domestic ones living in Rondonia, Amapá and Pará. I think that they could survive in the Neocene. My idea is that they would evolve into a smaller form, similar to the lowland anoa (Bubalus depressicornis). They would live in small herds, moving throught the rainforest. What do you think?
JOrnitho: Made a new description: Caracaraí, or giant caracara (Caracaraetus sicarius) Order: Falconiformes Family: Falconidae Habitat: Savannas and semi-arid regions of South America, also present in open coastal plains. While some species suffered heavily with human interference over the environments, some were able to benefit from that. The crested caracara (Caracara plancus) had thrived during the Holocene, benefiting from animals killed in roads, trash and fires caused by humans. It was with little difficulty that the lineage of this bird had survived into the Neocene, with the caracaraí being its descendant. Inhabiting the savannas and semi-arid regions of South America, the name of this bird was used by the people of Marajó Island to name its ancestor. The caracaraí is a powerful bird of prey, rivalling even the illapa in size. Their body length ranges from 89 to 110 cm. Males average about 90 cm in length, while females average about 100 cm. The wingspan is from 200 to 270 cm. Both sexes are mostly black to brownish black with strikingly white markings on the neck, the tip of both wings, and the tail. They have a bright red skin around their eyes. The beak is dark grey with the legs being yellow. Their claws are black With the size of a dagger. This species is specialized in hunting large prey such as deermaras, land caimans, giant tinamou, jacumitans, storks, herons, parrots and other birds of prey. Among those, hawks and falcons are their favored food. The caracaraí kill these birds while they are distracted hunting, using their strong claws to crush them. They also eat fishes and carrion, being able to dispute it with large vultures and young acatous, especially when working in pairs. Caracaraí is a monogamous bird, with mated pairs staying together even after the nesting season. Due to that, they can work together to bring down larger prey. The male will distract the prey, while the large female swoops down to do the kill. They breed during the end of spring and the middle of summer. The nest is a large, open structure, typically placed on the top of a tree or palm, but sometimes on rock formations. The typical clutch size is two white eggs with reddish spots. Incubation lasts about 28 days and is carried out by both parents. The chick leaves the nest around the third month of life, but continues to demand the care of its parents for four more months. Usually, only one of the chicks is raised by the parents, usually the one that hatches first. The youngest is killed by his sibling and eaten. Sexual maturity is reached with 2 years and they have a lifespan of 25 years.
JOrnitho: Reposting the Yara's description: Yara (Yara cancrivora) Family: Mustelidae Habitat: Brackish and coastal areas of Northern South America, Caribbean Islands and Gulf of Mexico. The anthropogenic onslaught over nature during the Holocene had damaged several ecosystems and brought several species to extinction. The disappearance of humanity gave some respite to the survivors and they continue to evolve, occupying niches completely new. The populations of tayra (Eira barbara) inhabiting the surrounding areas of Lake Maracaibo and the Gulf of Venezuela had gave rise to an aquatic species. This animal is the yara, which shares its name with a siren of the Amazonian folklore and in Tupi it means "the one that lives in the waters". The yaras are medium-sized aquatic mammals that inhabit brackish and coastal areas of the Northern South America, Caribbean Islands and the surrounding regions of the Gulf of Mexico. The males have 150 cm, while the females have 120 cm. The yaras have an elongated body, with a fin layer of fat, which helps the animal to float. Like seals, their paws are modified into flippers, with their hind flippers being bound to the pelvis in such a way that they cannot bring them under their bodies to walk on them.When compared to the body, the animal's foreflippers are relatively short with a slong claw and the hindflippers are slender. Small claws are present at the foreflippers, with a large one present at the forth digit. In the males, these claws have 25 cm of length, while in the females they barely surpass 15 cm. The fur is short and dark brown in the upperparts, with a cream underside. The pups are born with light brown fur and a white underside. They swim by sideways movements of their bodies, using their hind flippers to fullest effect. Because they cannot turn their hind flippers downward, they are very clumsy on land, having to wriggle with their front flippers and abdominal muscles. The yara have a vestigial tail, with only 8 cm. The head is rounded with an extended broad muzzle. The face has relatively large wide-spaced eyes, upward opening nostrils, and long light-colored and smooth whiskers. Unlike true seals, their ears are present, but very reduced. These mammals feed mostly on benthic animals, such as crustaceans and molluscs. They have strong and thick masseter muscles that help them crush exoskeletons and shells. Yaras can remain underwater for at least one hour. Most of their foraging happens at coastal areas during the day, with them being reluctant to hunt at open sea. They can also feed on fish and sea urchins, biting through the underside where the spines are shortest, and licks the soft contents out of the urchin's shell. The yaras will also follow Caribbean algocetus, taking the opportunity to catch benthic animals disturbed by these large herbivores when they are feeding. Male yaras are solitary and nomadic, constantly moving in search of food. When two males meet, they fight fiercely against each other, delivering bites and slaps with their foreflippers. These slaps can result in deep slashes from their long claws. On the other hand, the females form small colonies of close related individuals, usually an older female, her daughters and their cubs. Such groups can have from ten to twenty individuals. Males will visit the groups during the mating season, which starts in late spring and early summer. The female gives birth to only one pup after a gestation of 9 months. The family groups gather in sandbanks and protected beaches where the females give birth. The pups are born with fur, but their eyes and ears are closed. After three weeks they open and they start to interact with the other pups of the group. Within one month, the young follow the mother to learn how to forage at the sea, but they continue suckling. During this period, mothers can be seen floating in calm lagoons during the evening while their pups rest over them. They are totally weaned within 6 months and independent with 8. At this time the males are expelled from the group, while the females remain with their mothers. Females reach sexual maturity with 4 years, while males reach it with 5 years. Yaras have a lifespan of 35 years, but predators take some individuals during an early age. Among their main predators are the sharks.
wovoka: I think, this description even better than previous.
ìåäâåäü: Interesting animal!
JOrnitho: I made the description for a rodent: Caatinga digging hocicudo (Trypanomys vorax) Order:Rodentia Family:Cricetidae Habitat:Northeastern South America,the semi-arid xeric shrubland and thorn forests known as Caatinga. The species that now live in the Neocene are survivors of the calamities, caused both by humans and nature, that marked the end of the Holocene. Among the survivors were the rodents of the genus Oxymycterus. Popularly known as hocicudos, they had a great number of species spread through different biomes of South America. One of its descendants is the genus Trypanomys, the digging hocicudos. The type species of the genus is the Caatinga digging hocicudo, an inhabitant of the semi-arid xeric shrubland and thorn forests of Northeastern South America. The Caatinga digging hocicudo has a head to body length of 110 to 139 mm, with a moderately long tail of between 80 and 104 mm. The hind feet, including the claws, are 27 to 31 mm long and the ears are 18 to 20 mm. The snout is elongated making the head long and narrow. It’s flexible, allowing the rodent to move it around to detect smells. They have reduced eyes, short ears and short, soft fur. The dorsal color is light brownish, neither particularly darker in any region nor lined with black; ventral color pale yellowish wash, but with dark gray bases of hairs apparent. They have a patch of white that comes from the chin to the throat, a characteristic shared by all species of the genus Trypanomys. The upper surfaces of the hind feet are greyish brown. Its specialized body structure lends itself to the animal's subterranean life, with broad forefeet and large claws for digging. They have highly developed jaw muscles that help to close the mouth quickly, as to avoid swallowing dirt while digging. This species fills the niche of shrews and moles, mostly absent in South America. They live underground and eat invertebrates such as earthworms and insects. They consume half of their body weight in food each day. Caatinga digging hocicudos are active both during the day and the night. The Caatinga digging hocicudo is a solitary rodent, with a promiscuous reproduction. The males will mate with several females, dispersing through the population range to find them. Reproduction Happens during the entire year, but peaks happen during the rainy season. The female needs to be at an optimum weight to start the oestrum. Gestations last from 28 to 30 days, with the female giving birth to a litter of 5 to 10 naked and blind young inside a chamber lined with dry grass in the web of tunnels that they excavate. The weaning lasts for a month, with the young leaving their mother’s tunnels five weeks after that. They have a lifespan of 2 years. Other species in the genus Trypanomys are: Atlantic forest digging hocicudo (Trypanomys melanicus) This species inhabits the Atlantic forests in the Southeastern and Northeastern coast of South America. The Atlantic forest digging hocicudo has a head to body length of 109 to 134 mm, with a moderately long tail of between 70 and 97 mm. The hind feet, including the claws, are 26 to 30 mm long and the ears are 17 to 20 mm. The dorsal hairs have grey bases, orange midsections and blackish tips, giving an overall dark brown colour. The flanks have a wider orange band giving them a paler appearance. The underparts are orange, the individual hairs having grey bases. The upper parts of hind feet are light brown. Mountain digging hocicudo (Trypanomys serranus) This species is endemic to the “campos de altitude” ecoregion located at the Caparaó mountains. The mountain digging hocicudo has a head to body length of 107 to 129 mm, with a tail of between 67 and 90 mm. The hind feet, including the claws, are 23 to 29 mm long and the ears are 16 to 19 mm. Their overall dorsal coloration is predominantly dark brown. The individual hairs are blackish tips, narrow orange subterminal band, and slate gray base; sides of body slightly more orange due to wider pheomelanin band; venter orange but with slaty base showing through; ears dark brown and hind feet covered dorsally by grayish brown hairs. Pampa digging hocicudo (Trypanomys megacephalus) This species inhabits the low grasslands of the Pampas plains in South America. The Pampa digging hocicudo has a head to body length of 111 to 138 mm, with a moderately long tail of between 87 and 98 mm. The hind feet, including the claws, are 27 to 32 mm long and the ears are 18 to 20 mm. They are characterized by a large relatively large head if compared to the other species. Dorsal and lateral coloration of generally dark- brown from head to base of tail, with some specimens paler and more reddish- brown. The ventral color varies from orange to reddish orange; hindfeet covered dorsally by dark- brown hairs. Little digging hocicudo (Trypanomys savanicus) This species inhabits the savannas of central South America. The little digging hocicudo is the smaller species of the genus, with a length between 30 and 52 mm excluding the tail, which adds another 24 to 32 mm. The dorsal color is dark- brown to pale brownish red, without strong lining of black; ventral color dark gray to paler, cinnamon buff or pinkish buff. The upper hind feet are light greyish brown.
wovoka: Interesting rodents!

JOrnitho: What species of interesting small rodents you think that could evolve in the Neocene?
Chmumrikk: I think scaly-tailed squirrels (Anomalure) could be something interesting. African jungles persist in the Neocene, and some species may inhabit the land of Zinj. Besides, as far as I know, they are the best of all African rodents at climbing trees. It is also possible that the descendants of the Cameroon scaly-tail (Zenkerella insignis) may also survive. Although it doesn't quite fit the topic of the discussion.

I also believe that they could survive. Given its closeness with Cameroon, I even think that an anomalurid could reach the island of Bioko and evolve there. Sometime ago, I proposed a descendant of echimyid rodents with the abiltiy of glidding living in the Amazon. I also had an idea for a large descendent of the Atlantic bamboo rat (Kannabateomys amblyonyx).
