Late Jurassic, 150 million years ago
Ceratosaurus was a large theropod dinosaur that lived approximately 150 million years ago during the Late Jurassic period. This species was first discovered in North America, but later remains were found in Portugal and Tanzania. Ceratosaurus was named for the distinctive horn-like structure on its snout.
Ceratosaurus was a large dinosaur, reaching lengths of around 20 feet and weighing up to 1.5 tons. Its body was well-muscled, with powerful legs and sharp claws. It was a bipedal dinosaur, meaning it walked on two legs.
One of the most distinctive features of Ceratosaurus was the horn-like structure on its snout, which gave it its name. This horn may have been used for display or defense against predators, but the exact purpose is still not entirely clear. The dinosaur also had a small horn above each eye, as well as sharp teeth, which suggest that it was a carnivore that fed on other dinosaurs and small animals.
Ceratosaurus lived in a variety of habitats, including forests, swamps, and deserts. It is believed that this dinosaur was an opportunistic hunter, feeding on whatever prey was available. Some scientists think that it may have been a solitary predator, while others suggest that it may have lived in small groups.
Today, Ceratosaurus is one of the best-known dinosaurs, and remains of this species have been well-studied by paleontologists. Despite this, there is still much that we do not know about this fascinating dinosaur, and ongoing research continues to provide new insights into its biology, behavior, and evolution.
