Eygalayodon is a genus of very primitive ungulate that lived during the Eocene epoch of Europe. It belonged to the Dichobunidae family and represented one of the earliest known ungulates. In life, Eygalayodon would have resembled a very small duiker or chevrotain with a long tail. Each foot retained several toes with small hooves. They were probably fast-running animals due to their long limbs and slender build body. The shape of their teeth suggests they were browsers, feeding on small leaves in the undergrowth of dense forests or semi-open landscapes.
Eygalayodon montenati is one of two species within its genus and fossils have been found in France, dating from the Eocene epoch. It was a very small species, reaching just 12 cm in length (without its tail)!
