Dog skull, great colour and patina. Part of the heart wall

Part of the heart wall lifts off to expose the right atrium and both ventricles

These were part of a collection of medical bones that came from a retired doctor

The inner ear is removable to show the semi-circular canals etc

often using fine sand

The skull has been very well cleaned and bleached and came from an animal that died on the road

Dog skull, great colour and patina. Part of the heart wallThis is a real dog skull although I don't know what breed it is from. It looks to be about a spaniel sized breed. This skull has some of the best colour that I have seen on a skull. I can only assume that this has been lying either in peaty water or in a peaty area as the bone colour is a lovely caramel yellow colour which just highlights the white of the teeth. Unfortunately the lighting on the photographs did not show the colour off to it's best.
