And this folks is what happens when a bored, amateur paleoartist hits random on Dinopedia and then proceeds to look up a predator for the random kentrosaurid they got.

So a little about the dinos:
Chialingosaurus was a Late Jurassic kentrosaurid. It was found in Sichuan Province in China. Its age makes it one of the oldest species of stegosaurs.

Szechuanosurus, a dubious theropod from the roughly the same time period as Chialingosaurus, is only known by four teeth. I depicted mine based on the infographic by :iconteratophoneus:.

I might color this later but I spent enough time on the lines, that I don't particularly feel like it right now.
