Abstract: New Mexico has a sparse but growing record of Jurassic dinosaurs. The oldest records are
theropod footprints and a sauropod vertebra from the Middle-Upper Jurassic Summerville Formation.
The footprints are part of a widespread large theropod-pterosaur ichnofacies in the Summerville and equivalent strata in the southern Western Interior. The sauropod is one of the oldest North American sauropods. The oldest theropod eggshell is from the Upper Jurassic Morrison Formation in New Mexico. Most New Mexican Jurassic dinosaurs are from the Upper Jurassic Morrison Formation and include Apatosaurus, Diplodocus carnegiei, Diplodocus (=Seismosaurus) hallorum, Camarasaurus, Allosaurus, and Stegosaurus. These dinosaurs are part of a homogenous Morrison dinosaur chronofauna found throughout the Western Interior and characteristic of the Comobluffian land-vertebrate faunachron.
