They flourished for 150 million years, dominating the Earth. This period is known as the Age of Dinosaurs, and the Jurassic period was part of the dinosaur era. Dinosaurs came in many varieties, with sizes and shapes that were incredibly diverse. However, about 60,000 years ago, these dinosaurs suddenly and mysteriously disappeared, leaving behind only some fossils. What could be the reason for this? It remains a mystery to this day.
