Sinopa ("swift fox")[12] is an extinct genus of placental mammals from extinct clade Sinopinae within extinct order Hyaenodonta, that lived in North America and Asia from the early to middle Eocene.[13][14]
Description
[edit | edit source]Sinopa was a small genus of hyaenodontid mammals. Its carnassial teeth were the second upper molar and the lower third. Sinopa species had an estimated weight of 1.33 to 13.97 kilograms.[15] The type specimen was found in the Bridger formation in Uinta County, Wyoming, and existed 50.3 to 46.2 million years ago.
Taxonomy
[edit | edit source]The putative African species "Sinopa" ethiopica from Egypt was considered a species of Metasinopa by Savage (1965), although Holroyd (1994) considered it a potential new genus related to Quasiapterodon.[16]
