Name: Dromomeron romeri, D. gregorii, D. gigas
Name Meaning: Running Femur
First Described: 2007
Described By: Irmis et al.
Classification: Avemetatarsalia, Ornithodira, Dinosauromorpha, Lagerpetidae
Dromomeron is a genus of Dinosauromorph, specifically a Lagerpetid, a group of early-derived Dinosauromorphs from the Late Triassic. This group contains a handful of very small animals which were beginning to adapt for fast, upright, active movement - a foreshadowing of their later dinosaurian relatives. Dromomeron, specifically, lived about 220 to 211 million years ago, in the Norian age of the Late Triassic. It was about 1 meter long, and has three species assigned to it. D. romeri is from the Chinle Formation of New Mexico, known from a partial skeleton and other remains of hindlimb bones. D. gregorii hails from the Colorado City Formation of Texas, known from limb bones, and it was slightly older than D. romeri. D. gigas was found in the Quebrada del Barro Formation of Argentina. It, like other Ornithodirans, was an active animal, probably covered in filamentous integument, and would have lived alongside other Dinosauromorphs, including Dinosaurs proper, in complex Triassic ecological communities.
