In Depth

       A relatively small canid,‭ ‬Eucyon is one of the earliest true dogs to enter the fossil record.‭ ‬Living during the late Miocene it would have been in competition with larger and more dangerous predators such as the amphicyonids,‭ ‬however Eucyon and its relatives were better adapted to the on-going climatic changes of the Miocene.‭ ‬The earliest species of Eucyon such as E.‭ ‬davisi first appear in North America and parts of Asia during the Miocene,‭ ‬while later species of the late Miocene and early Pliocene are known from as far away as Europe and Africa.‭ ‬Although Eucyon would disappear at the beginning of the Pliocene,‭ ‬the true dogs would go onto become one of the dominant predator types all the way into modern times.
