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.
