Prothylacinus is an extinct genus of South American metatherian, that lived during the Early Miocene.[1]
Description
Prothylacinus had a vestigial hallux that was most likely not visible in life. The humerus bore the epicondylar foramen. In form it was similar to the related Borhyaena.[2] As with other Sparassodonts, the deciduous teeth are less reduced, only the canines and premolars changing.[2]
Distribution
Fossils of Prothylacinus have been found in the Friasian Río Frias Formation of Chile and the Santacrucian Santa Cruz Formation of Argentina.[3]
