Full Answer

The plates of the Stegosaurus served as radiators. As each plate contained a supply of blood vessels and alternated position as opposed to forming two rows, the plates were capable of releasing excess body heat or functioning as solar panels in colder environments. The bony, spiked projections at the end of the tail were likely used for defense, but it is possible they were ornamental, according to Encyclopaedia Brittanica.

    What are the two classes of dinosaurs?

    A:

    Beginning in 1887, dinosaurs have been divided into two main categories: saurischian, which means "lizard hipped," and ornithischian, which means "bird hipped."
