This is an internal mold of a highly modified bivalve, Ascaulocardium armatum (Morton, 1833). I have a couple of specimens from the spoil piles at Reedy Point, by the Delaware Canal, and also one from the Coon Creek in Mississippi.

The paper you want to get is:

Ascaulocardium armatum (Morton, 1833), New Genus (Late Cretaceous): The Ultimate Variation on the Bivalve Paradigm
John Pojeta, Jr. and Norman F. Sohl

Memoir (The Paleontological Society)
Vol. 24, Supplement to Vol. 61, no. 6 of the Journal of Paleontology (Nov., 1987), pp. 1-77

I also have one of these from the NJ Cretaceous. Took me a long time to figure it out. But you have to love the weird bits the most.

I would never, ever have guessed that this is a bivalve internal mold...

What an oddity!
