I am in need of skeletal specimens of digging mammals for teaching my Comparative Biomechanics course. I am open to models of other digging mammals as well. Thank you for any help you can provide.
Considering the costs and time involved in casting and reproducing a whole skeleton and the availability of the species you're looking for, I would suggest going for a real skeleton. You can get in touch with Skulls Unlimited as suggested, but they tend to be on the expensive side. You can also ask about it on the taxidermy.net forum, plenty of bone people & some museum people there as well. If you're willing to prep them yourself, it should be even easier to get some specimens.
