Hexagonaria ovoidea



Hexagonaria ovoidea coral found in the Jeffersonville Limestone of Jefferson County, Kentucky.  Creatures existed in the Middle Devonian Period (397-385 million years ago).  Thanks to my cousin for loaning me this specimen to photograph.

Is that a flat plate? Some of your pics show concave shapes and the rest are convex.

Yes, the plate ranges from 1.2 to 3.0 cm in thickness.

It consists entirely of the coral colony. Sorry for not clarifying which images are of the top and bottom surfaces of the plate.
