How this 3D skeleton was made
This 3D model is a reconstruction. Most bone shapes (297 of 316) are estimated from close relatives and published reconstructions. The bone shapes are not the actual shapes of this species' fossils. 19 bones were shaped from photos or figures of this species' own fossils.

Of the 316 bones (excluding teeth), 19 were modeled from photographs, drawings, and dimensions of actual fossils of this species; 0 were adapted in size by borrowing bone shapes from close relatives; and 297 were estimated.
