Medically prepared human disarticulated skull bones They breed in huge coloniesThese bones were part of a collection from a medical school museum. This is a collection of disarticulated skull bones comprising of the frontal, two parietals (both left) and a sphenoid. The parietals still have the medical school collection number on them.
