Here's all of the Cretaceous Period micro fossils from the quarter bucket of gravel I brought home from the creek trip Saturday. Pleasantly, surprised to find so much in so lil' gravel! Definitely, obtaining more if the opportunity arises again! In the picture: Scapanorynchus (Goblin Shark), Squalicorax, Ptychodus (pieces of Ptychodus teeth), Cretolamna, Pyncnodont tooth and Enchodus Palatine jaw piece, vertebrae, Gastropod, Pachyrizodus teeth, Ptychotrygon (Sawfish teeth), and Angel Shark tooth.
