Forelimb musculature and function in the therizinosaur Nothronychus (Maniraptora, Theropoda)
Journal of Anatomy, 2021AbstractTherizinosaurs are unusual theropods from the Upper Cretaceous of Asia and North America. North American representatives include Falcarius utahensis from central Utah, Nothronychus mckinleyi from west central New Mexico, and N. graffami from southern Utah. Nothronychus was quite large, with well‐developed forelimbs and pectoral girdle.

AbstractTherizinosaurs are highly modified, probably herbivorous, theropods from the Upper Cretaceous of Asia and North America. They are characterized by an extensively pneumatized axial skeleton, and in the derived forms, an incipiently opisthopubic pelvis. The evolution of such a pelvis is expected to be associated with extensive modification of the

Forearc basin deposits of the Yezo Group (Matsu-moto, 95; Okada, 982), Hokkaido, Northern Japan, yield abundant fossiliferous calcareous concretions. In addition to numerous ammonoids and inoceramids, these concretions contain various vertebrates, including teleosts, mosasaurids, elasmosaurs, both marine and ter-restrial turtles (Hirayama and Chitoku ...

The distribution of air-filled structures in the craniofacial and neurocranial bones of the oviraptorid ZPAL MgD-I/95, discovered at the Hermiin Tsav locality, Mongolia, is restored. Based on the complete obliteration of most of the cranial sutures, the specimen is identified as an adult individual of Conchoraptor gracilis Barsbold 1986. Except for the

ABSTRACT Many disarticulated bones from multiple individuals of a primitive therizinosaurian, referred to Falcarius utahensis, were found in the paucispecific Crystal Geyser bonebed in the Lower Cretaceous Cedar Mountain Formation of eastern Utah. To date, more than 2000 specimens from this species have been excavated.

ABSTRACT The recent discovery of a dense, paucispecific bonebed from the Early Cretaceous Cedar Mountain Formation, central Utah, has yielded new information on the morphology and evolution of therizinosaurs. Detailed description of the pectoral girdle and forelimb of Falcarius utahensis—the predominant taxon recovered from this site—provides the basis
