Miacis

Miacis ("small point") is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene.

==Description== Miacis was five-clawed, similar in size to a stoat (~30 cm, tail not included), weighed between 1 and 7 kg, and likely had highly reversible hind feet that assisted in its arboreal lifestyle, similar to those of a squirrel. It retained some primitive characteristics such as a low skull, a long slender body, a long tail, and short legs. Miacis retained 44 teeth, although some reductions in this number were apparently in progress and some of the teeth were reduced in size.
