Although a partial articulated skeleton is known, Dromomeron was mainly described through a femur. Much attention came from the fact that remains of this little bipedal animal have been found among those of dinosaurs indicating that the latter did not immediately replace their archosaurian relatives as previously thought. A second species of Dromomeron, D. gregorii has been recently (2009) described based on femurs from the Otis Chalk Quarry 3, Texas and the Placerias Quarry is near St. Johns, Arizona.
