Articulated metatarsals of a hypsilophodontid, probably Oryctodromeus |
In mid-August 2005 I assisted Dr David Varricchio (Montana State University) in the Cretaceous Blackleaf (Montana) and Wayan (Wyoming & Idaho) Formations. Here I helped collect the [now famous] burrowing dinosaur Oryctodromeus (Varricchio et al 2007), along with other hypsilophodont material, theropod eggshell, leaf impressions, and in extracting and identifying what is currently Idaho's largest known dinosaur: an undescribed ankylosaur. Varricchio, D.J., Martin, A. J. , and Katsura, Y. (2007) First trace and body fossil evidence of a burrowing, denning dinosaur. Proceedings of the Royal Society of London B , v. 274, n. 1616, p. 1361-1368. [PDF] hosted at Dr. Martin's homepage
