It was 30 degrees cooler today, and drizzling, when we returned to the site. We had one final bone to remove, a probable fibula (one of the bones in the shin). Everything went smoothly, and we were able to remove this last bone, which finished up our excavating for the season (I’ll be in Wyoming for a few more days, wrapping up loose ends and going to some geology sites).

One final point, on one of our vertebrae. I had suspected that the second vertebra we collected was an anterior caudal (tail) vertebra. Yesterday we visited the Wyoming Dinosaur Center, and I photographed this anterior caudal from Supersaurus:

Other than being at least four times bigger, it compares well with our vertebra:

It’s been a very successful excavation, and I’d like to thank all the folks that helped make it possible, including the folks at Shell Campground and Dirty Annie’s, as well as my seven volunteers.
