"300-Million-Year-Old Fossilized Skin Unearthed in Oklahoma Cave"

TL;DR
Paleontologists have discovered a 300-million-year-old piece of fossilized skin in an Oklahoma cave, belonging to a prehistoric lizard-like reptile and now the world's oldest preserved skin found. The fossils, found in the Richards Spur cave system, contain both the exterior and internal structure of the skin, providing valuable insights into the early land-dwelling creatures. The unique combination of clay-rich sediment, lack of oxygen, and seeping oil in the cave preserved the tough skin, making it an exceptional find in the fossil record.
