The ulna forms the pointy bit of our elbow as the olecranon process rotates about the trochlea. The olecranon of Serendipaceratops is broken and completely absent from the solitary ulna that was recovered. Due to the fact that the olecranon is missing our hypotheses about the shape of the elbow as a whole unit are somewhat lacking. The hypotheses that have been made are based on the olecranons of other neoceratopsians like Leptoceratops of Canada. Some of the subsequent studies mentioned yesterday have refuted this comparison as well however.
