Fruitafossor
''Fruitafossor'' was a termite-eating mammal endemic to North America during the Late Jurassic epoch (155.7—150.8 mya), existing for approximately .〔(PaleoBiology Database: ''Fruitafossor'', basic info )〕
The description is based on a surprisingly complete skeleton of a chipmunk-sized animal. It was discovered on March 31, 2005, in Fruita, Colorado. It resembled an armadillo (or anteater) and probably ate colonial insects in much the same manner as these animals do today. Other skeletal features clearly show that ''Fruitafossor'' was not related to armadillos, anteaters, or any modern group of mammal. This indicates that specializations associated with feeding on ants or termites have independently evolved many times in mammals: in ''Fruitafossor'', anteaters, numbats, aardvarks, pangolins, and echidnas.
==Description==
In 2009, a study by J. R. Foster was published that estimated the body masses of mammals from the Late Jurassic Morrison Formation by using the ratio of dentary length to body mass of modern marsupials as a reference. Foster concludes that ''Fruitafossor'' was the least massive of the formation at 6g, much lower than the average Morrison mammal of 48.5g.〔Foster, J.R. 2009. Preliminary body mass estimates for mammalian genera of the Morrison Formation (Upper Jurassic, North America). PaleoBios 28(3):114-122. 〕
