I reported last month on our Diplodocus pelvis from Shell, Wyoming, which we have been cleaning in our lab. We accomplished two milestones in its preparation today. We completed the preparation work on the left ischium, shown above (the right ischium was completed last month.)
We also removed the right pubis from its field jacket for the first time, and turned the bone over so we can clean the inside (medial) surface.
As you can see above, there is still a fair amount of sediment to remove on this side, as well as several cracks to glue and fill. Even so, this bone is remarkably well preserved, including some areas that are only a few millimeters thick.
