toe bone

A few weeks ago I started prep work on a Tyrannosaurus rex toe bone recovered from Montana's Hell Creek Formation and kept at the New Jersey State Museum. This is how the gypsum-encrusted bone looked when I started...
... and this is how it looked at the end of last week. There's still a lot of work to do, but it is encouraging when you start seeing more bone than gypsum.
