}}Allalmeia was a small notoungulate of around 3 kilograms. It lived in Mendoza Province, Argentina (Divisadero Largo Formation) during the Late Eocene.[2]

Description

It was a digitigrade mammal, with brachyodont and lophobunodont teeth. It had a generalized way of locomotion, that means, it could move easily in any terrain, but probably it preferred the safety of the forest trees where it lived. Although being an ungulate, Allalmeia had claws as the oldest mammals.[3]
