Biology:Yeutherium
Yeutherium is an extinct genus of mammal from the Reigitheriidae that lived during the Late Cretaceous (Late Campanian-Maastrichtian). Its fossils have been found in the Dorotea Formation in Chile and the type species is Y. pressor.[1]
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]
