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 ().
Ichthyosaur
During the Early Jurassic, the ichthyosaurs still showed a large variety of species, ranging from 1.0 to 10 m in length. From this epoch, the original British discoveries were made, so that among ichthyosaurs, their names are the ones most familiar to the general public. Genera include "Eurhinosaurus", "Ichthyosaurus", "Leptonectes", "Stenopterygius", and the large predator "Temnodontosaurus", along with the basal parvipelvian "Suevoleviathan", which was little changed from its Norian ancestors. The general morphological variability had been strongly reduced, however. Giant forms, suction feeders and durophagous species were absent. All of these animals were streamlined, dolphin-like forms, although the more basal animals were perhaps more elongated than the advanced and compact "Stenopterygius" and "Ichthyosaurus". The latter belonged to a parvipelvian subgroup, the Thunnosauria. These were fully adapted to an efficient thunniform locomotion, propelling themselves with the end of the tail only, equipped with a vertical tail fin. Their front flippers had more than five fingers. Another parvipelvian branch was the Eurhinosauria such as "Leptonectes" and "Eurhinosaurus", which were specialised forms having very elongated and pointy snouts.
