The Dentition of Lambdotherium

Abstract

The genus Lambdotherium is well represented in fossil vertebrate collections from Wyoming. Indeed, it is an important index fossil for the Lost Cabin zone in the continental Eocene of North America; but, curiously enough, a complete dentition belonging to a single individual never has been recorded. The description of such a specimen, therefore, seems worthy of record, particularly since the material reveals some important characters that hitherto were uncertain or unknown.
