Approximately 65 million years ago, dinosaurs suddenly vanished from the Earth, leaving behind a wealth of fossil records and countless unsolved mysteries. Scientists have proposed various theories in an attempt to uncover the truth behind this enigmatic event. Some believe it was due to the dinosaurs' own evolutionary failures, while others point to impacts from extraterrestrial bodies. Fossils excavated from ancient geological layers testify to the rise and fall of these colossal creatures. Dinosaurs were incredibly diverse, ranging from fierce carnivores to gentle herbivores, and exhibited significant differences in size and lifestyle. Over time, dinosaurs gradually lost their dominance, leaving behind a series of mysteries waiting to be explored by modern scientists.
