Closing in On the End of Scan Stitching

So I'm very close to posting an image of the fully digitized fossil material. There are a few pieces that a colleague of mine is finishing up, and I need to locate where the left dentary has run off to... It appears to not be among the files I've been working off of. There's one other place it could be, which is on the laptop that was used when scanning. I hope it's there so I don't have to rescan anything. There is also one dorsal vertebrae that seems to be missing data for about half of the bone....I am going to look into stitching an older scan of that bone together, from when we were using PET opposed to Geomagic. It will take a lot longer to stitch, but It would be better than having to schedule an entirely new scanning session.

In the meantime, here is an image of the skull. The skull was incredibly difficult to stitch together, since each fragment was very difficult to scan. Some of these pieces are being held together by a very thin layer of Paleobond glue. Because of the fragmented quality of the skull, as well as the complex shape in general, it was very difficult to get a complete scan. I worked with what we had and was able to get them pieced together as best I could. The skull is so fragmented though, and a lot of the detail that the scanner didn't pick up consists of the interior of breaks...i.e. material that wouldn't be visible if it was a complete skull. When the full skeleton is built, and the entire skull reconstructed,  it will not even be noticeable that some of these crevices were not picked up.

In the meantime, it's on to digging through the literature so I can start modeling the missing bones.
