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.

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.

Is there a little foramen at the top of it ? Because with the new pics you provided, it more looks like a brachiopod.

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.

Not a brachiopod. 

I'd agree with solitary rugose 'horn' coral.

Thank you all for the help! I really appreciate it, hopefully I can find more specimens to help identify this further
