How this 3D skeleton was made
This 3D model is a reconstruction. Most bone shapes (146 of 291) are estimated from close relatives and published reconstructions. The bone shapes are not the actual shapes of this species' fossils. 3 bones were shaped from photos or figures of this species' own fossils. 142 are borrowed from close relatives.

- 3D Skeleton: A reconstruction created on this site from freely usable materials (papers, public-domain books, Wikimedia photos) (2026-10-05). Out of 291 bones (excluding teeth), 3 bones were shaped directly from fossil photos, drawings, and measurements of this species; 142 bones were scaled from shapes borrowed from close relatives; and 146 bones were estimated.
