Description

edit

This was a large pig-like creature, larger than living species.

Fossils of males of these species show that they had large lumps on their muzzle and widely flaring cheekbones. Their tusks were only of moderate size. It can be assumed that the ornaments were used as a mating display.

Palaeoecology

edit

Dental microwear analysis of N. pattersoni fossils found at Kanapoi indicate that it was a mixed feeder, partitioning its dietary niche with Notochoerus jaegeri, which was a grazer.[3]
