Old Seabed Fossils of Some Sort.

Recommended Posts

I found this and many others in a stream near Dayton, Ohio. Its a piece of old seabed and contains dozens of fossils. I'm a VERY novice fossil hunter so I could use some help identifying everything that's going on with this one. I found a lot more at this location, if you want to see more, just let me know.  Also let me know if you would like more photos of this one.

Thank you to all who reply! :)

Neat find. This is what we colloquially call a "hash plate" because it is, well, a bit of a hash! Judging by how busy it is and the many disarticulated bits, it may have been a high energy environment. It's a little like the area was put in a blender and set on puree. :D In actual fact, it is usually the result of storm/wave action that works and reworks the sea floor and all the dead critters deposited there.

 

What dominates here would be the most intact items - brachiopods. There is likely also bryozoan pieces and other broken bits. I am guessing it would be Ordovician (or possibly Devonian) in age.

 

If there are specific parts you'd like to see identified, a close-up of those would be lovely. :)

Could also be Silurian. Need solid IDs to establish age.

I agree with what everybody has said, except that there is a specimen of an encrusting coral, Protarea richmondensis, on one of the brachiopods.

I was wondering what that was. I also see a few rings from a crinoid columnal.

Wow, it really gives a sense of the ecosystem that existed at the time. Later today I'll post pictures of more of the fossils I found at the site , that way we can see what else was there. Thank you everybody!
