What’s Older Than a Giant Tortoise?

If medals were awarded to animals for living a long time, then a giant tortoise would certainly win one. Some giant tortoises have lived for more than 150 years! Still, there are things on this planet much older than giant tortoises. Some of the giant sequoia trees that grow in California would be more than 3,000 years old. But the trees aren’t that old compared to the Barringer Crater in Arizona—that was made about 49,000 years ago. And it’s almost impossible to imagine that 65 million years ago, the T. Rex dinosaur roamed this planet—but we have the skeletons to prove it!
