Planetetherium is an extinct genus of herbivorous gliding mammal endemic to North America during the Paleogene living from 56.8 to 55.4 mya, existing for approximately 1.4 million years.[1]
Fossils have been discovered in strata formed from ancient cypress forests, suggesting that this was the animal's preferred habitat.
Morphology
[edit]Plantetherium is estimated to reach around 25 centimetres (10 in) in length, and its known materials closely resembled that of its modern relatives. Its teeth already included the comb-like structure distinctive to modern colugos. Since no postcranial materials have been described for any plagiomenid,[2] there is no direct evidence that Planetetherium had the membrane of skin that allows modern colugos to glide, but this was likely the case.[3]
