Mendel28 Posted July 28, 2021 Share Posted July 28, 2021 Hello everyone. My son and i are both passionate about paleontology. During our research’s, we found these stones in red clay/sand with flint dating from Cenomanian (near Chartres, France). The stones were among the remains of bivalves and sponges. All the fossils found show strong erosion. Do you think it could be fossils or just stones? Thank you Link to comment Share on other sites More sharing options...
abyssunder Posted July 28, 2021 Share Posted July 28, 2021 (edited) Welcome to TFF! As I see, there are are no rocks. First picture reminds me of bivalve fragments(some of them might be Rastellum sp.), second of rudist fragments(lower or upper valve terminals).

Mendel28 Posted July 29, 2021 Author Share Posted July 29, 2021 Thank you for your reply ! We hoped so much to have found very eroded mosasaurs teeth... Maybe another time Could you help me on this stone found today in the same layer (cenomanian)? The stone is fragile, it looks like spongy bone in its center. Perhaps it is a nodule of flint...

abyssunder Posted July 29, 2021 Share Posted July 29, 2021 I'm not sure what is in the last picture, perhaps the core of a flint nodule, I mean a possible sponge. (?)
