What is this bone?

We at the Centre for Forensic Anthropology Research at Cranfield University have just launched the What is this bone? service, where anyone can send us a good digital picture of any bone or bones they would like to be identified. We will try our best (as long as the quality of the photograph is good enough) to provide information about what type of bone it is, whether it is animal or human, juvenile or adult, archaeological or forensic, and any other information we can. Go on, test us!
