Biochemical sedimentary rock- in a biochemical limestone the calcium carbonate is locked into the fossil into the shells and skeletons of marine organisms.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
