Hi TNETTERS I took the concreation to the Cleveland Museum of Natural History. This is what the man in charge of fossil restoration said.....It's a piece of the skull and thoracic shield of dunkleorsteus terrelli. This ferious arthrodire fish was a preditor in the Devonian Seas of Ohio. The skull of this fish is nearly 1.4 meters long. This is a plate or part of the thoracic shield, approximately 360 million years old. The museum wants me to donate this and several other pieces of the skull. This skull is pictured on the front cover of 'Fossils of Ohio'. Thanks for the input!

So a fish, but not a flounder

The fossil piece posted about 12". If skull 1.4 meters reckon only about 20% of the skull. Pretty amazing and thanks for the update

jhenry have you donated the fossil, not sure where you found yours, read this to see if you can
keep it, about 10-12 yr ago someone found a fossil, and the state took it, not sure which
rule/law they used. from what i understand a find of artifacts in ohio, is best kept to yourself
http://www.dnr.state.oh.us/Portals/10/pdf/GeoFacts/geof17.pdf

and if you can sell it, try someplace like here, nice find, maybe mount it for your wall
oh and if you find an arrowhead, just enjoy it, as you wont be able to talk about, or
so, thats what ive heard, or maybe its where you talk about it at, IDK that archie thing
ya know,thanks for posting it
