Taxonomy

edit

Nothropus priscus and Nothropus nordenskioldi are described as subtaxa. Nothropus was named by Hermann Burmeister (1882). It was assigned to Megalonychidae by L. G. Marshall and T. Sempere (1991)[2] and to Nothrotheriidae by Christian de Muizon et al. (2004).[3]

Fossil distribution

edit

Fossils have been uncovered from the Tarija Formation, Tarija Department, Bolivia, east side of the Andes Mountains.[4]
