Ideas and Evidence in Science: The Kirkdale Cave
Evidence D - bone from cave
Points for students to consider:
This is a photograph of a bone found inside the Kirkdale Cave.
The gnawed ends of the bone and holes are believed to be caused by hyenas.
Pupils may need an example of a normal bone with which to compare it (if possible, a real sample of a bone should be used or a photograph could be sourced).
Pitting can be seen on the surface of the bone, which has been caused by the teeth of hyenas.
