Did Styracosaurus Have Good Posture?
We know what their horns looked like due to direct fossil evidence, but how do we know what their posture was like? Scientists can study the muscle attachment points on the fossils to determine how the bones likely went together. For ceratopsians, like Styracosaurus, there had been some question as to whether they stood straight-legged or with their legs bent and out to the sides. The leading theory now is that they stood with their legs slightly bent, but not as far out to the sides as crocodiles, because otherwise they would have had problems with dislocated shoulders.
