This slab was once part of an ancient seafloor that was uplifted and incorporated into mountains about 80 million years ago, long after the seafloor turned into thick layers of rock.The fossils preserved in this slab include early echinoderms (spiny-skinned marine invertebrate animals) known as echinoids and ophiuroids (brittle stars). The brittle stars are recognizable, with their five prehensile arms and the compact central body. They look very similar to living species of brittle stars,
