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 ().
Oplosaurus
The tooth is large, 85 mm (3.35 in) tall in total, with a spatulate crown 52 mm (2.05 in) tall, comparable to "Brachiosaurus"; it has a pointed tip, a slightly compressed form "cheek" to tongue, a slight convexity to the base of the tongue-facing side, and wear facets. It is vaguely like a "Brachiosaurus" tooth, which is why the genus has for a time been referred to the Brachiosauridae. Earlier, "Oplosaurus" was typically referred to "Pelorosaurus" following an opinion of Friedrich von Huene in 1909, although "Pelorosaurus" is based on fragmentary remains that do not include teeth, making it impossible to prove the identity. (See Naish and Martill (2001) for a good review of "Oplosaurus" and Wealden sauropods in general; here is a more recent informal summation of the state of work.)
