Not being paleobotanists, we kept on looking. The bone itself is very fragile. Working among a number of bones made for close quarters, and it took all our attention to keep from accidentally stepping on a bone while working in another section of the site. Our guide asked us to keep an eye out for the other half of this item. Someone in a previous dig had moved the rock, making it almost impossible to figure out where in the site it had come from.
All equipment is provided.
Just bring appropriate clothing and plenty of sunscreen. We opted for tee-shirts and shorts.
