Chitons are primitive marine molluscs in the class Polyplacophora (formerly the class Amphineura). There are 900 to 1,000 living species of chitons. Their size ranges from 0.5 to 30 cm in length; most are quite small. All the living species are in the subclass Neoloricata, and so may be called 'loricates'. Popular names are sea cradles or coat-of-mail shells.
How many types of dinosaurs are known? Approximately 700 species have been named. However, a recent scientific review suggests that only about half of these are based on fairly complete specimens that can be shown to be unique and separate species. These species are placed in about 300 valid dinosaur genera (Stegosaurus, Diplodocus, etc.), although about 540 have been named. Recent estimates suggest that about 700 to 900 more dinosaur genera may remain to be discovered.
