The giant dromaeosaurid taxon Dakotaraptor steini was described by DePalma and others (2015) based upon a partial skeleton and additional referred specimens. While the holotype consists of a single individual belonging to the taxon D. steini, Arbour and others (2016) mentioned that one element, the referred furcula, was an entoplastron from a trionychid turtle. We hereby revise the hypodigm of Dakotaraptor steini to exclude the referred “furcula” of PBMNH P.10.113.T, and the referred specimens NCSM 13170 and KUVP 152429. In its corrected form, the hypodigm is now comprised only of the confirmed dromaeosaurid elements referable to D. steini.

Most dromaeosaurids were small- to medium-sized cursorial, scansorial,
and arboreal, sometimes volant predators, but a comparatively small
percentage grew to gigantic proportions. Only two such giant “raptors”
have been described from North America. Here, we describe a new giant
dromaeosaurid, Dakotaraptor steini gen. et sp. nov., from the Hell
Creek Formation of South Dakota. The discovery represents the first
giant dromaeosaur from the Hell Creek Formation, and the most recent
in the fossil record worldwide. A row of prominent ulnar papilli or
“quill knobs” on the ulna is our first clear evidence for feather
quills on a large dromaeosaurid forearm and impacts evolutionary
reconstructions and functional morphology of such derived, typically
flight-related features. The presence of this new predator expands our
record of theropod diversity in latest Cretaceous Laramidia, and
radically changes paleoecological reconstructions of the Hell Creek
Formation.
