prehistoric creatures

Prehistoric creatures are animals that lived before written history, often millions of years ago. They include famous beings like dinosaurs, giant mammals, and early aquatic life. These creatures are known from fossils—preserved bones, teeth, or imprints in rocks—that reveal their appearance and ways of life. Studying them helps us understand Earth's biological past, how species evolved, and how ecosystems changed over time. Although they no longer roam the Earth, their legacy continues through the scientific insights they provide about our planet’s ancient history.
