Micah Posted August 16, 2017 Share Posted August 16, 2017 Hey all I'm clueless on this one. The vertical ridges and complete roundness of this piece aren't like anything I've found previously. I found this in a creek bed that runs through Oaks, Oklahoma among mostly brachiopods and bryozoans. Beyond the fact it's most likely aquatic my best guess is it's the tip of a piece of coral, but that really is a guess. Thanks in advance for the help!

ynot Posted August 16, 2017 Share Posted August 16, 2017 The pictures are badly focused, but it looks like a mold of the top of a horn coral. Better pictures could change that opinion.

Peat Burns Posted August 16, 2017 Share Posted August 16, 2017 Hard to be sure from the photos, and I don't know the time period of your locality, but shark dentacle (something like Petrodus) might be a possibility to check. Link to comment Share on other sites More sharing options...
Micah Posted August 16, 2017 Author Share Posted August 16, 2017 Shoot sorry about the picture quality, I'll add some better pictures. Link to comment Share on other sites More sharing options...
Micah Posted August 16, 2017 Author Share Posted August 16, 2017 @ynot here are some better pictures, hopefully they help. I'm not seeing any shark denticles that remotely resemble this, but thanks anyway @Peat Burns! Link to comment Share on other sites More sharing options...

Micah Posted August 16, 2017 Author Share Posted August 16, 2017 Could of be the tip of an urchin spine? Maybe Tylocidaris? Link to comment Share on other sites More sharing options...
ynot Posted August 16, 2017 Share Posted August 16, 2017 Thanks for the additional pictures. I still think it is a mold of the top of a horn coral. 1 Darwin said: " Man sprang from monkeys."

Miocene_Mason Posted August 16, 2017 Share Posted August 16, 2017 Another vote for coral, at least that's what my gut says. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
fifbrindacier Posted August 16, 2017 Share Posted August 16, 2017 I'll also vote for a solitary coral. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

Micah Posted August 17, 2017 Author Share Posted August 17, 2017 Do we have any coral experts? I appreciate all the input, but it possible I'd really like someone who's a bit more certain to confirm or deny whether it's the tip of a solitary rugose coral, or something else entirely.

Rockwood Posted August 17, 2017 Share Posted August 17, 2017 I recommend waiting. It could be, but I have doubts. Link to comment Share on other sites More sharing options...

I've got doubts too, I have found lots of coral, but none has ever looked like this. What really makes me doubt it most is how smooth the grooves and surface are. Coral tends to be porous, but this doesn't seem to have any of the typical tiny holes characteristic of the leftover skeletons of the tiny creatures that make up coral.

The tiny holes I think you are referring to are the corallites of a coral colony. This is a solitary coral - the entire thing is a single corallite.

TqB Posted August 17, 2017 Share Posted August 17, 2017 I'm with the mould of a solitary coral calice, can't easily tell if it's scleractinian or rugose though. Tarquin Link to comment Share on other sites More sharing options...

It is the dirt that filled in the top of a horn coral, making a mold of the living chamber. Notice that the matrix and the "mold" are the same material. 2 Darwin said: " Man sprang from monkeys."

I can definately see that now, Thanks!!! Link to comment Share on other sites More sharing options...
