Discovery and naming

The holotype was discovered in the Dorotea Formation in Chile and it consists of a partial maxilla with an associated molar.

Yeutherium pressor was named and described by Püschel et al. (2025). [1]

Description

Yeutherium was estimated to weigh around 30 ounces (850 g) when fully grown. [2] Its dentition was also specialised towards crushing food. [1]

Classification

Yeutherium was also found to be close to Reigitherium , and it was subsequently placed into Reigitheriidae as only the second genus in the family. [1]
