I'm a bit confused about the differences between a tetrapod and a dinosaur. Can you help me?

A tetrapod is an animal that has four limbs, while a dinosaur is an animal that has two legs and a tail. Dinosaurs are a subset of the group of animals called reptiles, which includes birds, lizards, snakes, and turtles. All mammals have four limbs. So, all mammals are tetrapods, but not all tetrapods are mammals!
