What animal species is armor covered and cold blooded?

The armadillo is an example of an armor-covered, cold-blooded animal species. While they are primarily known for their tough, protective shell, it's important to note that armadillos are actually warm-blooded mammals. However, if you are looking for cold-blooded species with armor, certain reptiles like turtles and some species of crocodilians also have protective shells or armored skin.
