The hands had four fingers: the first was short but strong and bore a large claw, the two following fingers were longer and slenderer with smaller claws, and the fourth was vestigial. The arms were powerful, with a long and slender upper arm bone. The neck was long, and its vertebrae were hollow, and very light. Most of the teeth had serrations at their front and back edges. Those in the lower jaw were much smaller than those of the upper jaw. The teeth were long, curved, thin, and compressed sideways. The mandible was slender and delicate at the front, but deep at the back. It had a pair of longitudinal, plate-shaped crests on its skull, similar to a cassowary with two crests. The snout was narrow, and the upper jaw had a gap or kink below the nostril. It was slender and lightly built, and the skull was proportionally large, but delicate. Dilophosaurus was one of the earliest large predatory dinosaurs, though it was smaller than some later theropods. At about 7 meters in length, with a weight of about 400 kilograms. The genus name means "two-crested lizard". Dilophosaurusis a genus of theropod dinosaur that lived during the Early Jurassic, about 193 million years ago.Gallimimus was toothless with a keratinous (horny) beak, and had a delicate lower jaw. The snout was long compared to other ornithomimids, although it was broader and more rounded at the tip than in other species. The head was small and light with large eyes that faced to the sides. The forelimbs were weak while the hindlimbs were proportionally long. The hands were proportionally the shortest of any ornithomimosaur and each had three digits with curved claws. The neck was proportionally long in relation to the trunk. Many of the vertebrae had openings that indicate they were pneumatic (air-filled). As evidenced by its relative Ornithomimus, it would have had feathers. Gallimimus is the largest known ornithomimid adults were about 6 metres long, 1.9 metres tall at the hip and weighed about 440 kilograms. Gallimimus is a genus of theropod dinosaur that lived during the Late Cretaceous period, about 70 million years ago.By the way pteranodon were pterosaurs, not dinosaurs. More fossil specimens of Pteranodon have been found than any other pterosaur, with about 1,200 specimens known to science, many of them well preserved with nearly complete skulls and articulated skeletons. They lived during the late Cretaceous geological period. Pteranodon (meaning "toothless wing" in Greek) is a genus of pterosaur that included some of the largest known flying reptiles, with wingspans over 6 metres.
Alan Grant would like say a few words about dinosaurs represented in this game. Before we start, world-famous paleontologist Dr.
