Natural History

Eubrontotherium

Eubrontotherium (lit. 'true thunder beast') is an extinct genus of horned brontothere that lived in North America and East Asia during the Late Eocene. The genus contains a single species, E. clarnoensis, known from fossils found in the Clarno Formation of Oregon and in the Ergilin Dzo Formation of Mongolia. Eubrontotherium fossils in Mongolia are younger in age than those in the United States; it is unclear if this has paleobiogeographical implications since relatively few fossils of the genus are known. Although it was not the largest animal in its environment on either continent, Eubrontotherium was a large and heavy brontothere, estimated to have weighed over two tonnes. Eubrontotherium had two short horns in front of its eyes, relatively smaller than the horns of its close relatives.
