Agriochoerus is an extinct genus of scansorial herbivore of the tylopod family Agriochoeridae, endemic to North America.[1]Agriochoerus and other agriochoerids possessed claws, which is rare within Artiodactyla, as well as likely being scansorial.[2][3]Agriochoerus was first described in 1869.[4]
Agriochoerus lived during the late Eocene and the Oligocene.[5] It was medium-sized, the estimated body mass for A. antiquus being about 85 kilograms (187 lb).[6]
