bericson Posted February 19, 2020 Share Posted February 19, 2020 I found a cave recently, located about 30 feet above a creek on a hillside. Inside the cave I found a chunk of sediment, hardened into a sort of conglomerate. I split open the rock and inside found this. I have no idea what it is, thinking maybe a seed of some sort. Also in the conglomerate were crinoids and clam shell fossils, so this stuff seems old to me. I am located in central Missouri, USA and would really appreciate your help in identifying what this is. It is just over 1 inch in length (25.4 mm) and about 1/4 inch thickness (6.35 mm). On one side, there is a sort of indention that still has some of the conglomerate material in it. The side pictured is what I consider the front and is not the side with the indention and conglomerate, just to clarify. Link to comment Share on other sites More sharing options...
fifbrindacier Posted February 19, 2020 Share Posted February 19, 2020 Could you show us photos of each face as well as the above, under and profiles please ? As it is it looks to have pectinid features but we need those other pics to narrow it down. Sophie. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

fifbrindacier Posted February 19, 2020 Share Posted February 19, 2020 Is there a little foramen at the top of it ? Because with the new pics you provided, it more looks like a brachiopod.

Manticocerasman Posted February 19, 2020 Share Posted February 19, 2020 I'd rather think a little horn coral 4 growing old is mandatory but growing up is optional. Link to comment Share on other sites More sharing options...
Shamalama Posted February 19, 2020 Share Posted February 19, 2020 Agreed, It looks like a Horn coral that was eroded prior to burial. If the rocks you found it in are Devonian in age, look up Aulacophyllum. Or it might be a similar genus. 3 -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted February 19, 2020 Share Posted February 19, 2020 Not a brachiopod. I'd agree with solitary rugose 'horn' coral. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
bericson Posted February 20, 2020 Author Share Posted February 20, 2020 Thank you all for the help! I really appreciate it, hopefully I can find more specimens to help identify this further Link to comment Share on other sites More sharing options...
