They are characterized by rows of osteoderms along the top of their neck, trunk and tail which graded with varying abruptness from the anterior plates to the caudal spines at a point posterior to the dorsal vertebrae.
These may have had a number of functions: display and/or thermoregulation for the broad flat osteoderms, defense for the spikes.
A reptile named Dravidosaurus was considered to be a stegosaur, but it was later proven to be a sea reptile instead.
In Walking With... seriesEdit
Stegosaurus appears several times during this episode. Most importantly, it drives off a pair of allosaurs after they killed one sauropodlet, but it has also killed another in confusion.
Al comes across a mating pair of stegosaurs and is driven away by them.
