Cretaceous New Jersey finds at Big Brook

[jonnyquest]

 

 While sifting the gravel banks at Big Brook, sometimes I will get a lump of matrix or clay in the screen. Anything strange gets saved for later. Here are some of those finds. 

Looks like some kind of plant.

This is a bivalve. Don't know the species.

Top one is an impression of Trigonia. Don't know about the bottom one.

Thank you so much for the ids. I thought for sure the first pic was some kind of plant because of the center vein. The last pics looked to me like  part of a  filled in root system or something.

The first impression is the bivalve Inoperna carolinensis .

Trigonia impression at the top and Cardium at the bottom, I believe.

That shell imprint with the Trigonia, I believe is Ethmocardium welleri. Your bivalve finds, especially the Inoperna, are quite remarkable. Congratulations.

I second the value of those three mollysc impressions. Way better than the typical phosphatic steinkerns.

Thanks for ID's.
