Reconstruction of the forelimb musculature of the Cretaceous ornithopod dinosaurOryctodromeus cubicularis: implications for digging

Taphonomic and morphological evidence suggests that Oryctodromeus cubicularis, a basal ornithopod dinosaur from the mid-Cretaceous of Montana, constructed burrows by digging with its forelimbs. Reconstruction of the forelimb musculature of Oryctodromeus was carried out using the extant phylogenetic bracket method, with crocodilians and ratites as the extant analogues, aided by the presence of osteological correlates in Oryctodromeus and other...
