Symmetrodonta 

an order of fossil mammals that lived from the end of the Triassic to the early Cretaceous. Symmetrodonta were small animals, no larger than martens.

They are known from deposits in Europe and North America, where jaws and teeth have been found. Symmetrodonta were closely related to Pantotheria.
