A quick post from something on the hard drive…
Often, when inspecting corals(Cnindaria) or sponges(Porifera) that I have found in the Millersburg mb. of the Lexington, I find micro-fossils at the base of the colonies. It could be coincidental, but I’m starting to think that the micros were juveniles and that their progenitor placed the off spring in a habitat that favored survival, or the ones placed there were more likely to survive… which seems more plausible.
Anyway, here is a small bivalve that was collected from just such an environment.
A little closer
Since the common bivalves from the Millersburg are modiomorphids or ambonychiids, These are probably ambonychiids… probably Bysonnychia sp. juveniles.
