Hemicyon, also known as the "dog-bear" (literally "half dog", from Greek ἡμι- hēmi- (half) + κύων kúōn (dog)), is an

Amphicyonids (bear-dogs), which are their own separate family of carnivores
.

Morphology

Hemicyon was about 1.5 metres (5 ft) long, and 70 centimetres (28 in) tall, with and carnassial blades on its teeth for cutting meat. Hemicyon is widely accepted to have been

metapodials. This suggests that Hemicyon must have been an active hunter and a good runner, and presumably hunted by pursuing prey on open ground.[3]
In life, the genus would have looked something like a combination of a dog and a bear.

Fossil sites

Species of Hemicyon are recognized in the medial Hemingfordian (ca. 18 million years ago)

Santa Fe Formation
, New Mexico.

Hemicyonidae fossil evidence may also have been found in the Gaillard Cut Local Fauna, former Canal Zone, Republic of Panama, but it is indeterminant with Amphicyonidae. Despite its close proximity to South America, given the geological context, the Gaillard Cut Local Fauna are distinctly North American fauna and the age of this assemblage is dated between 19.5 and 14 Ma.[5]
