9949 Brontosaurus
This minor planet was named after Brontosaurus, a gigantic quadruped sauropod dinosaurs, which walked on all four legs and lived in the Upper Jurassic. Adult individuals measured up to 20 meters and had a weight of up to 20 tons. Many Fossils have been found in the United States. Brontosaurus is one of the best-known dinosaurs. The official naming citation was published by the Minor Planet Center on 20 November 2002 ().
Dilophosaurus
"Dilophosaurus" was one of the earliest large predatory dinosaurs, a medium-sized theropod, though small compared to some of the later theropods. Slender and lightly built, its size was comparable to that of a brown bear. The largest known specimen weighed about , measured about in length, and its skull was long. The smaller holotype specimen weighed about , was long, with a hip height of about , and its skull was long. A resting trace of a theropod similar to "Dilophosaurus" and "Liliensternus" has been interpreted by some researchers as showing impressions of feathers around the belly and feet, similar to down. Other researchers instead interpret these impressions as sedimentological artifacts created as the dinosaur moved, though this interpretation does not rule out that the track-maker could have borne feathers.
