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 ().
Coronosaurus
"Coronosaurus" is a medium-sized centrosaurine ceratopsid. Gregory S. Paul in 2010 estimated its body length at five meters, its weight at two tonnes. It had as an adult inflated supraorbital horncores — the "brow horns" above the eye sockets — but not elongated as in "Zuniceratops", chasmosaurines, and more basal centrosaurines (like "Albertaceratops" and "Diabloceratops"), that project laterally (to the sides) over the orbit. As a sub-adult its postorbital horncores are pyramidal in shape with a slight lateral inflection of the distal, upper, one half.
