Fruitafossor

Fruitafossor was a termite-eating mammal of North America during the Upper Jurassic epoch (about 150 million years ago).

The description is based on a surprisingly complete skeleton of a chipmunk-sized animal. It was discovered in 2005, in Fruita, Colorado. 

The animal looked like an armadillo (or anteater) and probably ate termites in much the same manner as these animals do today (ants had not yet evolved). Other skeletal features clearly show that Fruitafossor was not related to armadillos, anteaters, or any modern group of mammal. This means that specializations associated with feeding on ants or termites have evolved many times in mammals: in Fruitafossor, anteaters, numbats, aardvarks, pangolins, and echidnas.
