Summary:
- Divers in the Carolinas are exploring underwater caves and sinkholes that provide a glimpse into the Miocene epoch, a geological period that occurred around 23 to 5 million years ago.
- These underwater portals, formed by the collapse of ancient limestone caverns, contain fossils of extinct shark species that thrived during the Miocene, such as the megalodon and the extinct great white shark.
- The exploration of these unique underwater environments is providing valuable insights into the evolution and diversity of ancient marine life, helping scientists better understand the past and how it relates to the present-day ocean ecosystems.
