Which of the following reptiles has a muscular part of the stomach called a gizzard?

Ventriculus gastric mill, or gizzard, is a kind of muscular stomach found in birds and earthworms, as well as some types of fish and reptiles. The gizzard is special because it grinds up difficult-to-digest foods, making it particularly useful to animals that lack teeth. A gizzard features a hard, horn-lined surface with which to grind food. Although tough, animal gizzards are edible and are eaten all over the world.

Despite having sharp teeth, both crocodiles and alligators have gizzards. These reptiles don’t really use their teeth for chewing. Instead, their teeth have the more frightening job of trapping and killing their prey. With no grinding teeth with which to chew meat, the job of breaking down food falls to the reptile’s gizzard. Just like birds and earthworms, they swallow stones to aid in this process. Crocodiles and alligators are the only reptiles, so far known to science, that have gizzards.
