Dinosaurs

Ceratosaurus

means "horned lizard" which gives its name to the Ceratosauria, a clade of theropod dinosaurs that diverged early from the evolutionary lineage leading to modern birds. This was a carnivorous theropod dinosaur in the Late Jurassic period (Kimmeridgian to Tithonian).

Plesiosaurus

an extinct marine sauropterygian reptile that lived during the early part of the Jurassic Period. It is distinguishable by its small head, long and slender neck, broad turtle-like body, a short tail, and two pairs of large, elongated paddles.

Brachiosaurus

it part of sauropod dinosaur. American paleontologist Elmer S. Riggs named the dinosaur Brachiosaurus altithorax; the generic name is Greek for "arm lizard" (specific name: "deep chest"). Brachiosaurus is estimated to have been between 18 and 21 meters (59 and 69 ft).

Stegosaurus

part of herbivorous thyreophoran dinosaur. Fossils of this genus date to the Late Jurassic period which lived alongside dinosaurs such as Apatosaurus, Diplodocus, Brachiosaurus, Allosaurus, and Ceratosaurus. These were large, heavily built, herbivorous quadrupeds with rounded backs, short fore limbs, long hind limbs, and tails held high in the air.

Allosaurus

("different lizard") was a large bipedal predator. Its skull was large and equipped with dozens of sharp, serrated teeth. It averaged 9.5 metres (31 ft) in length, though fragmentary remains suggest it could have reached over 12 m (39 ft). Relative to the large and powerful hindlimbs, its three-fingered forelimbs were small, and the body was balanced by a long and heavily muscled tail.

Rhamphorhynchus

("beak snout") were part of long-tailed pterosaurs. Had needle-like teeth, which were angled forward, with a curved, sharp, beak-like tip lacking teeth, indicating a diet mainly of fish and cephalopod(squid).
