Long before humans walked the Earth, prehistoric creatures ruled the land, sky, and sea. Mammoths roamed icy landscapes, saber-toothed cats hunted in ancient forests, and giant sloths dominated the Americas. These animals were the predecessors of many modern species.
Many of these creatures thrived for millions of years before going extinct due to climate changes, habitat shifts, or human influence. Today, fossils and preserved remains provide clues about their incredible lives and adaptations.
