There was a light rain this morning, but we still headed out the site only about an hour late. There was a brief additional delay from the pronghorns standing in the road (yes, that dirt path is the road to our site)!
By late morning the weather had cleared, and we made a lot of progress. The first bone we uncovered, which I originally thought might be a giant rib, turns out to probably be a small scapula (shoulder blade):
Brett found the very fragile bone shown below while working on the scapula (it’s also just visible at the top of the scapula picture above). I believe it is part of the spine of either a cervical (neck) or dorsal (back) vertebra. We were also able to jacket this bone today.
