I have a large artistic sort of carving that is laced with Orthoceras fossils. I've attached a picture of one of the larger fossils. Now, the shell of the animal fossilizes well and that's easy enough to see. What I'm wondering is if the much-less-clear stuff at the big end of the shell is actually fossilized fleshy bits that managed to mineralize enough to leave an impression. I know that the fleshy bits of, well, anything really, don't usually fossilize well, so I'm wondering if I have a fairly cool fossil squid relative, or a cool fossil shell with random junk at the end. any thoughts would be appreciated. Thanks.
