This site is loaded with large quantities of Brachiopods, in great variety.
They are scattered all over the ground. You can't miss them.
This slab is typical of a particular layer on the site. On this slab has lots
of Eochonetes. They look just like Sowerbyella,
which are found in the Kope Formation. There are also a few Lepidocyclus
There also a number of the interesting Brachiopod, Leptaena.
This is a single valve with the distinctive shape of a Plaesiomys
The specimen below is not a Brachiopod at all. It's a fragment of the
Pelecypod, Caritodens. Note the growth line pattern. This is an easy way to
identify the Caritodens, one of the few clams in the Cincinnati
rocks that shows shell material.
These trace fossils are harder to identify. This slab (below) is covered with small indentations, that may had been what remains of clams or possibly inarticulate brachiopods. In either case, the shell material on these animals did not survive the test of time, but their impressions did.
This rock (below) has the opposite. Instead of indentations, there are convex
shapes. It's anyone's guess what these are, in this case. They are probably the
internal molds of clams. The guys got a kick out of their shape and suggested we
draw our own conclusion.
The next fossil is probably the ornate gastropod, Phragmolites.
I didn't get a good look at it, so I'm not sure if it has the ornate pattern,
characteristic of Phragmolites..
Membership Chairperson, Debby Scheid, found a very nice coiled cephalopod
with some shell material left. Here it is.
This trace fossil has a really nice set of Pyrite crystals.
This is a nice chunk of Calcite crystal with pointy structures. (Hey, I'm not
in the Mineral Society
That's all! (enough?)
