Hillbenny Posted April 6, 2022 Share Posted April 6, 2022 I found this on top of the ground while mushroom hunting. I have collected arrowheads, fossils, and other odd/cool looking rocks for a number of years but have never seen anything like it before. I found it a few miles south east of Calhoun,Missouri close to Henry county road NE 300, and a few yards from Tebo creek. I appreciate any help identifying what it is and approximately how old. 2 Link to comment Share on other sites More sharing options...
digit Posted April 6, 2022 Share Posted April 6, 2022 I'm getting a brachiopod vibe from this one. @Tidgy's Dad Cheers. -Ken 5 Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted April 6, 2022 Share Posted April 6, 2022 Brachiopod steinkern methinks. 1 5 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
digit Posted April 6, 2022 Share Posted April 6, 2022 Seemed to show internal features of brachiopods (from the little experience I have with them). Cheers. -Ken 3 Link to comment Share on other sites More sharing options...
Hillbenny Posted April 6, 2022 Author Share Posted April 6, 2022 Please excuse my ignorance, is a Brachiopod something like a clam or muscle?...I thought it looked like it had, well for lack of a better term, a "face" . I think I see a head, and a mouth with two teeth sticking up. But I honestly have no idea. Should I try to take it out of the rock that it's in? It looks like it is separated from the rock around it. But I don't want to do anything to break it or screw it up, though I'm very curious as to what it looks like underneath Link to comment Share on other sites More sharing options...

A brachiopod is similar to bivalves such as clams but they aren't very closely related. Bivalves are mollusks like snails and squids while brachiopods are not. They have several anatomical differences but they do resemble clams. “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor. It felt like home. It still does" -Mike (Pagurus) “The best deal I ever got was getting accepted as a member on The Fossil Forum. Not only got an invaluable pool of knowledge, but gained a loving family as well.” -Doren (caldigger) "it really is nice, to visit the oasis that is TFF" -Tim (fossildude19) "Life's Good! -Adam (Tidgy's Dad) Link to comment Share on other sites More sharing options...

Totally different and unrelated group of animals. But they do have two valves like clams and mussels. Yours is an orthid, maybe something like Hebertellla. I would leave it in the matrix myself. 3 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

But I don't want to do anything to break it or screw it up, though I'm very curious as to what it looks like underneath No. What you have is the mold formed of a mineral that solidified inside of the shell. Most of the shell has weathered away, except for a bit here and there between the mold and the rock matrix. There is nothing inside of it. It is what was inside the shell after the animal died and its body rotted away. The hard shell was left behind and preserved, eventually filled by a mineral in solution that, from the looks of it, crystallized inside, and the shell began to dissolve and/or be eroded away leaving the mold behind. That crack/space between the mold and the rock is where the shell used to be. 4 Mark. Fossil hunting is easy -- they don't run away when you shoot at them!
