Dinosaurs Barchiosaurus (22 to 30 meters long; 30 to 80 tons weight) was a larger dinosaur than Apatosaurus , and for many years was considered the heaviest of the sauropods. Brachiosaurs, as shown below, were different from other sauropods in having their forelegs longer than their hind legs, as well as having their nostrils high on the forehead. The largest known doinosaur, Ultrasaurus , either belongs to the brachiosaurs or is in fact a large specimen of Brachiosaurus , according to some paleontologists. The remaining saurishian dinosaurs were theropods, the bipedal carnivores exemplified by Allosaurus . Deciphering the evolutionary relationships of the theropods is difficult due to the often fragmentary nature of theropod fossils. Current thought is that there were several groups of theropods, and that one group, the carnosaurids contained the largest of the carnivores such as Allosaurus . Another theropod group was the coelurosaurids, which containd the birds and smaller carnivores such as ornithomimids, "raptors", and the tyrannosaurs.
