Partial disarticulated skull medical specimen. Frontal, parietals and one temporal bone.
Another partial disarticulated medically prepared skull. This one has the frontal bone, the two parietals and one temporal bone. These are all matching and from the same skull. Unfortunately, the remainder of the bones are now absent.
I think that this must have been a later example or did not have much use as the bones are still very clean and white.
