The Cretaceous Period, lasting from approximately 145 to 66 million years ago, is often referred to as the "Age of Dinosaurs" due to the dominance and diversity of dinosaur species during this time.

Sauropods, such as the famous Brachiosaurus and Diplodocus, were massive herbivores with long necks, tails, and pillar-like legs. They were the largest land animals to ever exist.

Mosasaurus was a giant marine reptile that lived during the Cretaceous Period. It could grow up to 50 feet long and was a fearsome predator, preying on other marine creatures.

Pterosauria, or pterosaurs, were flying reptiles that lived alongside dinosaurs during the Mesozoic Era. They had wings formed by a membrane stretched between their elongated fourth finger and their body.

The Chicxulub Impact, which occurred approximately 66 million years ago, is believed to have caused the extinction of dinosaurs and many other species. It left a massive crater on the Yucatan Peninsula in Mexico.

Triceratops was a large herbivorous dinosaur with a distinctive frill and three horns on its head. It lived during the Cretaceous Period and was one of the last surviving dinosaur species before the extinction event.

Quetzalcoatlus was a giant pterosaur that lived during the Late Cretaceous Period. It had a wingspan of up to 39 feet, making it the largest flying animal ever known.

Theropods were a group of carnivorous dinosaurs that includes species like Velociraptor and Deinonychus. They were characterized by their bipedal stance, sharp teeth, and long tails.

Plesiosaurs were a group of marine reptiles that lived during the Mesozoic Era. They had long necks, small heads, and paddle-like flippers for swimming.

Hadrosaurus was a duck-billed dinosaur that lived during the Cretaceous Period. It had a large, flat beak and could walk on both two and four legs.

Compsognathus was a small, bird-like dinosaur that lived during the Jurassic Period. It was about the size of a chicken and weighed only a few pounds.

Ichthyosaurs were a group of marine reptiles that lived during the Mesozoic Era. They had streamlined bodies, long snouts, and powerful tails for swimming.

Argentinosaurus was a massive sauropod dinosaur that lived during the Cretaceous Period. It is estimated to have been over 100 feet long and weighed up to 100 tons.

Stegosaurus was a large herbivorous dinosaur with a distinctive row of bony plates along its back. It lived during the Jurassic Period and was one of the most well-known dinosaurs.

Megalosaurus was the first dinosaur species to be discovered and named. It was described by the English geologist William Buckland in 1824.
