Upper Cretaceous dinosaur footprints from Grant County, New Mexico
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.
