Polished Fossil (IMAGE) Princeton University Caption This polished fossil slab used in the study dates to more than 210 million years ago and contains well-preserved symbiotic corals. The fossils were collected in a mountainous region in Antalya, Turkey, and originated in the Tethys Sea, a shallow sunlit body of water that existed when the Earth's continents were one solid land mass called Pangea.
