I just got done removing the largest and best of them from right next to the skull.
Here's a picture of the side of the Nautiloid with two limb bones in front of it. First I have to remove the two limb bones: they will be in a later post after they are prepared. I can tell they have hollow ends like all the other limb bones.
After I've removed the two limb bones, another nautiloid is revealed. This one appears to be crushed, and only part of it came out initially. I'll try to get more of it out later.
The smaller piece of Nautiloid clearly shows the siphuncle- the internal tube passage from one chamber to the other. Now that the large Nautiloid is out of the way, we can get at the deep part of theback of the skull. From a preliminary look it appears to be split completely front to back down the middle, and we only have one-half. However, this is actually excellent as it will reveal lots of the internal anatomy when prepared. I'll update information about the skull in the next post - major change in our concepts coming!
