Usage

The term "reptile genus" is used in scientific contexts, specifically in zoology and paleontology, to classify and discuss groups of reptilian species. - Alligator is a well-known reptile genus native to the Americas and China. - The reptile genus Tyrannosaurus contains some of the largest known carnivorous dinosaurs. - Biologists are debating whether to split the reptile genus Anolis into several new genera.
