@karen-metcalf This looks like a mastodon tooth to me. Even if it is some other kind of tooth it is a super find!

@greg-kessinger Canadian pebble is probable. The material on the surface would not have survived the glacial action that rounded the pebble. My thought is that this is a post glacial mineralogic creation, perhaps caliche?
From my own experience, I have a small pebble that I found as a kid that was split in two with both sides together. It is red sandstone (?) and inside is the impression of a Devonian brachiopod. So this one made it from Canada to Dayton, Ohio.
The other improbable specimen was found by a fellow Dry Dredger here in Cincinnati. This was a small slab with a complete well preserved Devonian Phacops trilobite from the Toledo, Ohio area. How that survived is unimaginable.

Further study of these specimens through thin section analysis reveals an internal structure equivalent to the type specimens for Solenopora. I have changed the classification here to reflect that.

Jen, I just realized I missed your point. Yes, this can be added to the other one. I don’t know why I thought you were deleting it altogether. Sorry.

7045 is the only image that shows arrows illustrating growth direction. Viewers don’t have to think about what I am trying to convey that this thing is growing in a 360 degree manner. If you just want pretty pictures of the fossils then you can eliminate this one but I did this to convey a point.

Probably but that would be assuming I knew how to do that 🙂

One cheat is that large trackways have to be either Isotelus or Eurypterid. The later would be exceedingly rare. Also, the Isotelus tracks have a trifid ending on the nicely preserved ones while Flexis won’t.

I agree with Bill – Protarea richmondensis – a coral
