Abstract

A detailed study of the dentition of Arnebolagus leporinus, the oldest lagomorphs, from the basal Eocene of Mongolia (age 55 million years) allows to consider it as an ancestor of the branch of “modern lagomorphs” (eulagomorphs). Within this branch, the ancestral group of modern hares, rabbits, and pikas has separated about 35 million years ago.
