Pennsylvanian Seed

I found this in the Finis Shale of the Graham Formation, in Jacksboro Texas. I'm told it's a seed but would like to know if that's correct and what kind. It's 7mm

Looks more like a bivalve to me

I agree.

See if you can find a paper describing Carpolithes acuminatus in greater detail. :)

Seed small, narrowed up from a rounded base to a sharply acuminate apex; surface smooth or shining, hard.

The seeds referred to this species are five millimeters long, three millimeters broad toward the inflated round base, often smaller, preserved imbedded into the shale in their original state of turgescence, never flattened. They are generally largest near the base, gradually narrowed to a sharp acumen, sometimes oval-oblong, acuminate at one end, obtuse at the other.

I originally thought it was a brachiopod but the suggestions of bivalve have the same problem...no suitable candidate. The description for Carpolithes acuminatus fits well enough but I haven't found an illustration for comparison. I did however find photos of three different kinds of Trigonocarpus sp. and one of them fits pretty well. I don't know why I never looked in the Dallas Paleo Occasional Papers article about this site, it would have saved me lots of confusion :wacko: Thanks for the replies.
