A large carnivorous dinosaur, Allosaurus was a formidable predator with sharp teeth and strong claws. It measured about 8.5 metres in length and hunted other large dinosaurs. Ankylosaurus was a heavily armored herbivore, growing up to 9 metres in length. It had a club-like tail it used to defend itself from predators. Known for its long neck and large size, Brachiosaurus was a giant herbivore that could grow up to 25 metres in length. It used its long neck to reach leaves high up in trees. Ceratosaurus was a carnivorous dinosaur that measured about 6 to 7 metres in length. It had a prominent horn on its snout and powerful jaws, making it an effective predator. One of the most well-known Late Triassic dinosaurs, Coelophysis was a small, slender, bipedal carnivore. It measured about 3 metres in length and had a long, narrow skull with sharp teeth. Corythosaurus was a herbivorous dinosaur, measuring about 9 metres in length. It had a crest on its head that may have been used for communication. Deinonychus was a small, agile predator with a sickle-shaped claw on each foot used for hunting. It grew up to 3.4 meters in length. Dilophosaurus was a medium-sized carnivore with two distinctive crests on its head. It measured about 6 metres in length and was a fast and agile hunter. Diplodocus was one of the longest dinosaurs, measuring about 25 metres. This giant herbivore had a long neck and tail, which it used to reach high vegetation and defend itself. Edmontosaurus was a large herbivorous dinosaur, growing up to 12 metres in length. It had a flat beak and a robust body, ideal for grazing. Euoplocephalus was an armored herbivore, measuring about 6 metres in length. It had spikes and a clubbed tail for defense. One of the first dinosaurs ever discovered, Iguanodon was a large herbivore. It could walk on two legs or four and had a distinctive thumb spike, which it likely used for defense. Iguanodon grew up to 10 metres in length. Ornithomimus was a fast-moving, omnivorous dinosaur, measuring about 4 metres in length. It resembled modern ostriches and had a beak. Pachycephalosaurus was a herbivorous dinosaur, famous for its thick, domed skull. It measured about 4.5 metres in length. Pachyrhinosaurus was a herbivore, growing up to 6 metres in length. It had a bony, flattened growth on its nose instead of horns. Parasaurolophus was a herbivore, measuring about 10 metres in length. It had a long, backwards-curving crest on its head. Pentaceratops was a herbivorous dinosaur with five prominent horns. It could grow up to 8 metres in length. Saurolophus was a herbivore, growing up to 9 metres in length. It had a long, flat crest on its head. Known for its distinctive plates along its back and spiked tail, Stegosaurus was a large herbivorous dinosaur. It grew up to 9 metres in length and used its tail spikes for defense against predators. Styracosaurus was a herbivore, growing up to 6 metres in length. It had a large frill and multiple horns on its face. Torosaurus was a herbivorous dinosaur with a large frill and two prominent brow horns. It could grow up to 9 metres in length. Known for its three horns and large frill, Triceratops was a herbivorous dinosaur that could grow up to 9 metres in length. It used its horns for defense against predators. One of the most famous dinosaurs, Tyrannosaurus Rex, was a massive carnivore with a powerful bite. It measured about 12 metres in length and was a top predator in its ecosystem. A large and fearsome predator, Utahraptor was a member of the dromaeosaur family. It had sharp claws and teeth, with the largest claw on its foot used for hunting. Utahraptor measured about 6 metres in length. Apart from dinosaurs, many other amazing animals fossils have been found in USA. These flying reptiles had wingspans that could reach over 7 metres. Pteranodons had long, toothless beaks and were likely fish-eaters, using their keen eyesight to spot prey from the skies. Known for their extremely long necks, which could measure up to 7 metres, Elasmosaurus had small heads and sharp teeth, perfect for catching fish. They were strong swimmers, with flippers that allowed them to glide gracefully through the water. This giant marine reptile could grow up to 21 metres in length. Resembling modern dolphins, Shonisaurus had elongated bodies, paddle-like limbs, and were likely fast swimmers. They fed on fish and other marine creatures. These formidable predators could grow up to 18 metres long. With powerful jaws filled with sharp teeth, Mosasaurus were apex predators in their marine environments, preying on fish, turtles, and even other marine reptiles. Dimetrodon, whose name means "two measures of teeth," was a prehistoric reptile that lived during the Early Permian period, around 295 to 272 million years ago. Despite often being mistaken for a dinosaur, Dimetrodon is actually more closely related to mammals. It is famous for its large sail-like structure on its back!
