More sperm whale

It looks like Apple may have finally fixed their server problems (at least, if you’re able to comment on this post they have done so).

The photo above shows the left dentary, still in the jacket. It has an oddly deformed area, indicated by the arrow.

If we look at the jacket from the side, it becomes apparent how this deformation occurred:

The arrow is indicating a second bone that has punched through the dentary. I believe this bone is the postorbital process of the frontal, a projection of the frontal bone the sticks down behind the eye socket. When the skull was crushed down onto the lower jaw, the postorbital process was pushed through the dentary.

Another interesting feature was revealed when the right dentary was removed. There was a thin layer of sediment, just a few millimeters thick, separating the dentary from the skull. This sediment contained several trace fossils, burrows formed by some type of invertebrate, like the one shown below:

    I’m in Indiana for the rest of the week, visiting friends, but next week I hope to work on this whale some more. The next task is to get the left dentary removed from the skull. That’s going to be a little tough, because of the skull bone sticking through it. It’s really deformed and fractured the dentary, so I’ll have to see how it goes.

    Once that’s out of the way, I should be able to prepare the rest of the skull.
