Amazing what you find out by talking to people online, I’d previously had a good look round for archaeology related Apps and found a fair few, mainly heritage walks round archaeological sites (see http://digitaldigging.net/archaeology-apps-heritage-apps/ for a good list). Also found a field walking App that seems to have since disappeared and BillionGraves which is aimed at getting people everywhere to record gravestones!
But have just come across Dactyl, which looks like the beginning of a very useful digital library of bones, with and without fractures, pathology and so on. Bit pricey at the moment for the number of bones available, but given time could be very handy. See http://intarch.ac.uk/journal/issue38/5/atkin.html for a review of Dactyl and similar skeleton visualisation tools.
