Borhyaenidium is an extinct genus of hathliacynid sparassodont that lived in South America during the Miocene and Pliocene epochs.1

Distribution

The type species, Borhyaenidium musteloides, inhabited Argentina,2 as did Borhyaenidium riggsi.3 Borhyaenidium altiplanicus lived in Bolivia.4

Description

B. altiplanicus had a significant diastema between P1 and P2 and a smaller one between P2 and P3. The P2 was slightly longer mesiodistally than the P3. The talonid of its M1 was unbasined and small. The talonid was larger on M2, which also had a hypoconid and hypoconulid that were both larger than the diminished entoconid.5
