New material reveals the pelvic morphology of Caenagnathidae (Theropoda, Oviraptorosauria)

Caenagnathids were oviraptorosaur theropods characterized by elongate hind limbs that are proposed as adaptations for either wading or enhanced cursoriality. A lack of well preserved pelvic material, however, has thus far prevented reconstruction of both the hind limb and girdle for verification of these hypotheses. Here we describe an abundance of new caenagnathid pelvic material from the Dinosaur Park Formation of Alberta, Canada. These new...
