 1. Dinosaurs: Dinosaurs were a diverse group of reptiles that lived from  245 million years ago to 65 million years ago. They range in size from small, bird-like creatures to huge, long-necked creatures like Diplodocus and  predators like T-Rex. 

 

 2. Trilobites: Trilobites were an extinct group of  marine arthropods that lived from the early Cambodian period (521 million years ago) to the late Persian period (252 million years ago). They were among the first animals to develop powerful eyes and  came in many forms. 

 

 3. Mammoths: Mammoths were a group of large, woolly, elephant-like mammals that lived during the Upper Paleolithic period. They had long, curved muscles and were well adapted to cold environments. The best-known species is  the woolly mammoth, which went extinct about 4,000 years ago. 

 

 4 They were known for their long, curved teeth that they used to capture and kill their prey. 

 

 5. Whales: Whales are a group of marine animals that resemble spiral shells. They lived from the Devonian period (419 million years ago) to the end of the Cretaceous period (66 million years ago). 

 

 6. Megalodon: Megalodon is a type of prehistoric animal that lived from  23 million to 3.6 million years ago. It is one of the largest animals ever, with teeth that can grow up to 19 centimeters. 

 

 7. Archeopteryx: Archeopteryx was a small bird-like dinosaur that lived during the late Jurassic period (150 million years ago). It had wings and wings, but it also had teeth and a long, bony tail. 

 

 8. Triceratops: Triceratops is a type of herbivorous dinosaur that lived during the Late Cretaceous Period (68 to 66 million years ago). It had a large head with bones on its head and three horns that were probably used for defense. 

 

 9. Megafauna: Megafauna refers to a group of large, prehistoric animals that lived during the Pleistocene period (approximately 2.6  to 11,700 years ago). These include animals such as the woolly rhinoceros, giant ground sloth, and toothed cat. 

 

 These are just a few examples of the many creatures that existed before humans. There are also many other interesting 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.
