    Like almost any slab from the type-Cincinnatian, it is loaded. There are fragments of the brachiopods Rafinesquina and Zygospira, a pygidium (tail) and partial cranidium (head) of the trilobite Flexicalymene, numerous trepostome bryozoans (unidentifiable beyond that), and columnals of the crinoid Cincinnaticrinus.

    It’s an endocerid nautiloid, and the clue is what looks like a large tube (called a siphuncle) inside the larger shell. The upper half of your fossil is the siphuncle, and a little bit of the siphuncle projects at the bottom. The entire shell would have been much, much longer, and it would have been occupied by a squid-like animal.
