Sinopa ("swift fox") 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.
Description
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.
The
type specimen was found in the Bridger formation in Uinta County, Wyoming, and existed 50.3 to 46.2 million years ago.
Taxonomy
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
