Description
Life restoration

Sinopa was a small hyaenodontid. Its carnassial teeth were the second upper molar and the lower third. Sinopa had an estimated weight of 1.3 to 1.4 kilograms. The type specimen was found in the Bridger formation in Uinta County, Wyoming, and existed 50.3 to 46.2 million years ago.[2]

Taxonomy
Sinopa rapax

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.[3]
