Dakotaraptor steini

(Stein's Dakota plunderer)Etymology
Dakotaraptor is derived from "Dakota" (for the US State where it was found, and to honour the Dakota First Nations Tribe) and the Latin "raptor" (plunderer, snatcher, robber or thief). The species epithet, steini, honors paleontologist Walter W. Stein.
Discovery
The remains of Dakotaraptor were discovered in the Hell Creek Formation of Harding County, South Dakota, U.S.A, by Robert DePalma in 2005. The holotype (PBMNH.P.10.113.T) includes a right thigh, both shins, the left anke and heel, some toe bones, one fragmentary back vertebra, 10 tail vertebrae, both arms and some finger bones from an adult specimen. What were initially interpreted as furculae ("wishbone"), including 2 referred pieces (KUVP 152429 and NCSM 13170, found 9 meters and 16 miles from the holotype respectively) turned out to be trionychid turtle entoplastra (pieces of armour from the underside of the shell).
