Upper Cretaceous dinosaur footprints from Grant County, New Mexico
Spencer G. Lucas and Charles A. Ferguson

Abstract:

We describe two dinosaur trackways from the lower part of the Mancos Formation (Upper Cretaceous, upper Cenomanian) near Silver City in Grant County, southwestern New Mexico. These trackways consist of deeply-impressed footprints that include large imprints of the posterior metatarsals, which suggests walking in a wet substrate. They were made by relatively small theropod dinosaurs (estimated hip heights of 1-1.6 m). These are the only Late Cretaceous dinosaur tracks known from southwestern New Mexico.
