20123 - Nice 1.72 Inch Pterosaur (Coloborhynchus) Tooth Cretaceous KemKem Otodus in matrix is an important tectosilicate mineralNice specimen. Not restored or glued. The teeth with strong and vivid fossilization colors such as red, orange and black come from small paleochannels composed by thin layers, in the intermediate and upper stratigraphic levels (Red Sandstone Beds), from the Aoufous Formation and Ifezouane Formation (Kem Kem Basin, South of Morocco).
