Large scales. Usually means much the same as plate, lamina, shield (Peters 1964).
The hard leathery plates found on the backs of animals such as crocodiles and dinosaurs. They are usually heavily thickened plates of skin material that act as an armoured shield on vulnerable areas such as the back and legs. Some reptiles also have bony scutes that are embedded into the skin. Occasionally dinosaur skeletons are found that have these bony scutes scattered around their bones; these have fallen off as the body decomposes.
Another word for keratin scales. Refers especially to the keratin scales on the outer layer of turtle shells. Sometimes called horny scutes.
