I found this very hard piece of rock,unlike the rest of the matrix,I dont know what it is.Its dark in color and is completely unbreakable with the needle(as contrast to the oreodont jaw,which i made a few scratches while prepping unfortunately)
If anyone could help me out identifying the following I'd really appreciate it a lot... The coral is a little bit crystallized - petrified, I found it in a beach near Cabo San Lucas, Baja California, Mexico The black polished fossil, was a gift, and there is not a clue of information The shells are from the coast of Portugal, and the fossilized snail I found it near Zacatecas, Mexico The Sedimentary Rock, I can't remember where I got it...so maybe because of the different colors and shape someone has a clue... Thanks again....
