Teeth and Claws

What is the largest raptor claw found to date in the world?

To date, the largest raptor claw found in the world belongs to the Therizinosaurus, which had claws that measured around 28 inches (70 centimeters) long. This theropod beast lived in the area now called the Mongolian Desert 75 million years ago. It was a long distant relative of other ferocious meat-eaters like the Velociraptor and the Tyrannosaurus. But it’s unknown how it used these huge claws because no one has ever found a complete skeleton of the creature. Scientists speculate that the claws may have been used for defense, mating displays, or—because it is thought that these theropods differed from most by eating primarily vegetation—even to reach treetops to forage on leaves.
