The guide told me to be careful, because snakes like to live in the bone cavities. We saw quite a few elephant skeletons, but no tusks! Because the government rangers collect the tusks, to prevent the poachers getting them. They reputedly have a huge warehouse full of tusks, waiting for the world embargo on ivory trading to finish. Botswana has a total ban on hunting, and consequently has a problem with elephant overpopulation.
