Real human medical partial skull sagittal section
This is a nice an quite unusual item. A medically prepared skull that was cut lengthwise to give the sagittal section. This nicely shows the exposed sinuses. The skull also has a piece removed to show the frontal sinus.
The hooks and pins are still in place showing that there would have been a removable cranium and mandible articulating on springs. Unfortunately, over the years these have become separated from the skull and gone missing.
There are also only a few teeth left in the jaw. The skull is surprisingly clean and white for the age which would suggest that it has not had a lot of handling over the years.
