Description
Illustrated by the talented Sheather888.

During the Late Paleocene, the most common medium-sized predator on the northern continents was the 3.5m Dromaeosaurine Dromaeosaur genus Boreoraptor. This animal was a close relative of Dakotaraptor and Dromaeosaurus, and generally resembled those genera while possessing a stockier build. First discovered at the Wannagan Creek Site in deposits dating to c.62 mya, this genus appears to have undergone quite a significant radiation. Indeed, at the present time, up to six or possibly seven species have been uncovered from sites in North America, Europe and Asia. Quite why this animal became so successful is not fully understood, but it may have something to do with the spread of the small North American Rhododromines into Europe and Asia. As these little Ornithischians probably formed a significant portion of Boreoraptor's diet, it follows that these animals simply followed their prey to pastures new. The species you see above is Boreoraptor acutus, which lived in China about 58 mya. Contemporary animals found alongside B. acutus include Jiangxialestes minor, a 1.8m relative of Saurornitholestes, the derived Pachycephalosaur Ornatotholus and an as yet unnamed Hadrosaur.
