Apatemyidae
Apatemyidae is an extinct family of placental mammals that took part in the first placental evolutionary radiation together with other early mammals such as the leptictids. Their relationships to other mammal groups are controversial; a 2010 study found them to be basal members of Euarchontoglires. Common in North America during the Paleocene, they are also represented in Europe by the genus '' Jepsenella''. Apatemyids in life Like most Paleocene mammals, the apatemyds were small and presumably insectivorous. Size ranged from that of a dormouse to a large rat. The toes were slender and well clawed, and the family were probably mainly arboreal. The skull was fairly massive compared to the otherwise slender skeleton, and the front teeth were long and hooked, resembling those of the modern aye-aye The aye-aye (''Daubentonia madagascariensis'') is a long-fingered lemur, a strepsirrhine primate native to Madagascar with rodent-like teeth that perpetually grow and a special thin ...

Apatemys
''Apatemys'' is a member of the family Apatemyidae, an extinct group of small and insectivorous placental mammals that lived in the Paleogene The Paleogene ( ; British English, also spelled Palaeogene or Palæogene; informally Lower Tertiary or Early Tertiary) is a geologic period, geologic period and system that spans 43 million years from the end of the Cretaceous Period million yea ... of North America, India, and Europe. While the number of genera and species is less agreed upon, it has been determined that two apatemyid genera, ''Apatemys'' and ''Sinclairella'', existed sequentially during the Eocene in North America. The genus ''Apatemys'', living as far back as 50.3 million years ago (mya), existed through part of the Wasatchian and persisted through the Duchesnean, and ''Sinclairella'' followed, existing from the Duchesnean through the Arikareean. Examinations of specimens belonging to the genus ''Apatemys'' suggest adaptations characteristic of arboreal mammals. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
