Vertebral pneumaticity of the North American therizinosaurNothronychus

David K. Smith et al.

Summary: Nothronychus is a large, derived therizinosaur from the Upper Cretaceous of Utah and New Mexico, with extensively pneumatized axial skeleton. It is inferred to have possessed avian-like abdominal air sacs.

Fernando E. Novas et al.

Summary: Unenlagia comahuensis was originally considered a link between nonavian dinosaurs and birds, but recent studies suggest it is more closely related to birds, sharing derived anatomical traits with them. This supports the interpretation that unenlagiids are stem-Avialae, providing new data on the early evolution of avian features.
