We believe education is the greatest gift osteology can share and that every human specimen can contribute to the advancement of science. These specimens are provided to us by retired physicians, medical researchers, dental professionals, and former university medical programs. We also work with accredited donor programs. A small sample – often antiques that simply do not qualify for medical/research grade usage – are made available to osteology enthusiasts worldwide so that they may continue to educate and inform.nSpecifications:nnSold individuallynnSold as-is without further cleaningnThe photo shown is an example of what your specimen will approximately look like.
