1. Dinosaurs: Dinosaurs were a diverse group of reptiles that lived from about 245 million years ago to 65 million years ago. They ranged in size from small, bird-like creatures to massive, long-necked herbivores like Diplodocus, and carnivorous predators like T-Rex.
2. Trilobites: Trilobites were a group of extinct marine arthropods that lived from the Early Cambrian period (about 521 million years ago) to the end of the Permian period (about 252 million years ago). They were among the first animals to develop complex eyes, and they came in a variety of shapes and sizes.
3. Mammoths: Mammoths were a group of large, hairy, elephant-like mammals that lived during the last ice age. They had long, curved tusks and were well adapted to cold environments. The most famous species is probably the woolly mammoth, which went extinct about 4,000 years ago.
4. Saber-toothed cats: Saber-toothed cats were a group of large, carnivorous mammals that lived from the Eocene epoch (about 56 million years ago) to the end of the Pleistocene epoch (about 10,000 years ago). They were known for their long, curved canine teeth, which they used to catch and kill prey.
5. Ammonites: Ammonites were a group of marine animals that looked like spiral shells. They lived from the Devonian period (about 419 million years ago) to the end of the Cretaceous period (about 66 million years ago).
6. Megalodon: Megalodon was a species of prehistoric shark that lived from about 23 million to 3.6 million years ago. It was one of the largest predators to ever live, with teeth that could grow up to 7 inches long.
7. Archaeopteryx: Archaeopteryx was a small, bird-like dinosaur that lived during the Late Jurassic period (about 150 million years ago). It had feathers and wings, but also had teeth and a long, bony tail.
8. Triceratops: Triceratops was a species of herbivorous dinosaur that lived during the Late Cretaceous period (about 68 to 66 million years ago). It had a large, bony frill on its head and three horns, which it likely used for defense.
9. Megafauna: Megafauna refers to a group of large, prehistoric animals that lived during the Pleistocene epoch (about 2.6 million to 11,700 years ago). This includes animals like the woolly rhinoceros, giant ground sloth, and saber-toothed cat.
These are just a few examples of the many creatures that lived before humans. There were also many other fascinating animals, such as giant sloths, pterosaurs, and ancient sharks. The history of life on Earth is a rich and diverse tapestry, and there is much to learn and discover about the creatures that came before us.
