Taxa from all three majors dinosaurian clades have been recovered, including theropods, sauropodomorphs, and ornithischians. Quinn recognized the fossilized remains as dinosaurian and prepared the bones. These new features gave Godzilla a more reptilian/dinosaurian appearance. Sereno's analysis of "Herrerasaurus" also led him to propose several new dinosaurian synapomorphies. This provides further evidence of the dinosaurian origin of birds. He is also a strong proponent to the view of a dinosaurian origin of birds. As part of this development, the rate of dinosaurian discoveries quickly picked up. However, only rarely are so many dinosaurian predators found at the same site. The tail of "Plateosaurus" was typically dinosaurian, muscular and with high mobility. More specimens were present that in 2008 were reported as representing several dinosaurian species. The status as a (dinosaurian) humerus is problematic.
