How many ceratopsians are there?
Over time, paleontologists have slowly uncovered a great deal of information. In 2018, the number of different species of Ceratopsian dinosaurs that had been identified was at forty. More than half of those discoveries were made in the last ten years. Paleontologists have uncovered full sets of many Ceratopsian bones.
Is Stegosaurus a ornithischian?
Towering giants such as Tyrannosaurus rex and Apatosaurus are both saurischians, but many plant-eating dinosaurs, including Triceratops and Stegosaurus, are classified as ornithiscians—which means bird-hipped—because their pubis bone was originally thought to resemble that of birds.
