About Agriochoerus
Agriochoerus is an extinct genus of scansorial herbivore of the tylopod family Agriochoeridae, endemic to North America. Agriochoerus and other agriochoerids possessed claws, which is rare within Artiodactyla, as well as likely being scansorial. Agriochoerus was first described in 1869.
Agriochoerus lived during the late Eocene and the Oligocene. It was medium-sized, the estimated body mass for A. antiquus being about 85 kilograms (187 lb).
