MPCN-PV 69; small to midsized theropod skeleton: partial premaxilla, 3 probable dorsal vertebrae, fused sacral vertebrae, proximal half of both L & R humeri, distal portion of pubis, & incomplete pedal ungual phalanx, plus some indet. frags. The grade of fusion of the neural arches to the centra indicates the specimen is probably adult or at least subadult. Total length is difficult to specify because it is highly fragmented, but is estimated to be 3–5 m long. | ||||||||||
