Anaptomorphinae is a pre-historic group of primates known from Eocene fossils in North America and Europe and later periods of Paleocene Asia, and are a sub-family of omomyids. The anaptomorphines is a paraphyletic group consisting of the two tribes ''Trogolemurini'' and ''Anaptomorphini''. Anaptomorphine radiation in Wyoming, one of the most detailed records of changes within populations and between species in the fossil record, has provided remarkable evidence of transitional fossils. ==Description== The primate evolved anagenetically. (Bown and Rose 1987) ''Teilhardina'' is the most primitive of the anaptomorphines with respect a number of dental features (e.g. four premolars and relatively unreduced canine). Most scientists recognize at least fourteen ''genera'' of anaptomorphine. The probable lineages of ''Tetonius'', ''Absarokius'' and ''Anemorhysis'' evolved from ''Teilhardinia'' or a closely related form from North America. The primates ''Tetonius'' and ''Shoshonius'' have by interpretation (Beard ''et al''; 1991) had classification within the ''Tarsiiformes'', therefore not belonging to human evolution. The Anaptomorphine population was apparently high during the Early Tertiary. ''Tetonius'' from the Early Eocene was first found in the late nineteenth century and is considered important due to the significance of the find in the forming the phylogeny of the primates. The last known animal belonging to the group was ''Trogolemur''. A fossil discovered in Utah was a new species of Trogolemur. Analyses of over hundred specimens of omomyid primates recovered in the Wasatch formation in Wyoming, suggest that anaptomorphines never developed the highly specialised molars seen in modern prosimians. Similarly, incisor enlargement was most likely an adaptation for grooming and food manipulation rather than a purely frugivorous or insectivorous diet. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Anaptomorphinae」の詳細全文を読む スポンサード リンク
