The closest living relatives of Stegosaurus are the only surviving dinosaurs, the birds. After birds, crocodilians are the next closest relatives. That is followed by other reptiles such as lizards.
Stegosaurus was a stegosaurid dinosaur. Stegosaurs belong to the clade Thyreophora, which in turn belongs to the order Ornithischia, or bird hipped dinosaurs. Dinosaurs are archosaurian reptiles, and reptiles are a class of vertebrate animals.

Stegosaurus was 23 to 30 feet long. Large animals like that don't usually have dwellings, and they don't use caves. Stegosaurus was probably the same. Their habitat was a semi-arid subtropical plain with distinct wet and dry seasons. Near rivers, there were forests of conifers, cycads, ginkgoes, ferns, and horsetails. Further from the rivers there were open areas covered in ferns with scattered trees. It is believed that Stegosaurus preferred the drier fern fields.
The son of your First counsin is your First cousin, once removed. The son of your Second Cousin is your Second Cousin, once removed. The son of your First Cousin, once removed, is your First cousin, twice removed. etc. So the child of your any-kind-of-cousin is the same-kind-of-cousin, removed once more than your any-kind-of-cousin is from you.
"Cousin" is a common noun.
Your first cousin's son is your first cousins once removed. Your second cousin's son is your second cousin, once removed. Your 10th cousin's son is your 10th cousin, once removed. The child of any kind of cousin is that kind of cousin, once removed.
When you "kind of like him" you should leave it as friends. Go for his cousin!
Stegosaurus lived 80 million years before Triceratops evolved. They were both herbivores, so they wouldn't have been natural enemies even if they had lived at the same time. If they had lived at the same time though, they probably wouldn't have been "friends" either, because most species only form relationships of any kind with animals of their own species.
Baby Stegosaurus would have made an easy meal for almost any carnivorous dinosaur, even small ones like Ornitholestes. However, Stegosaurus lived in herds and the parents would have done their best to protect the youngsters. Adult Stegosaurus did have predators, though. Carnivorous dinosaurs large enough to hunt adult Stegosaurus include Ceratosaurus, Torvosaurus, Allosaurus, Epanterias, and Saurophaganax.
Stegosaurus teeth were a pentagonal shape, but with more rounded, blunt corners. The upper edge of the tooth had lots of little rounded serrations in it, making the tooth look almost like it was some kind of leaf.
