Prehistoric ungulates were hoofed mammals that lived millions of years ago. They belong to a diverse group that includes ancestors of modern horses, cows, and deer. These animals adapted to various environments, from forests to grasslands, and played crucial roles in their ecosystems. Many prehistoric ungulates, such as the woolly mammoth and saber-toothed cat, coexisted with early humans. Their remains have been found in fossil records, providing insights into their size, diet, and behavior. Understanding these ancient creatures helps scientists learn about evolution and the changes in Earth's climate and habitats over time.
