Limestone fossils.

[A. Grignon]

Come across them once in a while since I moved to Fond du Lac, Wisconsin. All in limestone.
Used to be a underwater sea here and about 20 miles south of here they found a huge squid in a limestone quarry. Any way......here they are.....I think one is some kind of shell pokin out. Then the other two were found in the same spot same day. One is some kind of coral and the other looks like some kind of little sea plant, but if some one has a better idea of what to call that thing please let me know!

The "little shell poking out" is the lip of a horn coral. The pleated fossil is, I think, the head of a crynoid (a sea animal that looked like a flower - possibly Batocrinus - great find) and the other larger chunk is a Syringopora coral

Nice finds. That last pic is definitely NOT a crinoid. It is, however, another coral. Not sure which one. Thanks for the look.

You may be right. I saw that it was branching from the base to finer tips and figured a group of criniod arms without the basal cap.

Looks mighty like a fossil in my Field Book of North American Fossils listed as a Batocrinis crinoid head, though (Not the inage above, that's just an example of a crinoid for comparison). The one in my firld guide does have the calyx/basal cap.

Charlie, I can see why you would think so but, I would say it is definitely a coral. Is that your Crawfordsville crinoid plate? If so it is super nice. I have actually collected in a few localities in NY state. I have collected Devonian stuff near Buffalo and Ordovician near Utica. Have you ever collected those localities by chance? Here is a pick of some Phacops from the NY Devonian. The enrolled example, however, is from our Silica shale here in Ohio.

No (sadly) the plate I lifted off the Internet. I did get a chance to pull an enrolled Phacops at Portland Point on Cayuga Lake along with some other trilobite partials. Cargill used to be pretty understanding but now, with liability & probably the request of Cornell and the Palentological Research Institute they chase off fossil hunters from the best trilobite site locally (widely known for the primo Phacops samples). I'll see if I can get him to cooperate for an image.
