113-million-year-old pterosaur found
Researchers from James Kirk University in Brazil have discovered a rare fossil of a pterosaur wing bone dating back 113 million years, remarkably well-preserved despite the passage of time. The fossil shows signs of steroids and bacterial reactions involving sulfur oxidation, reflecting a unique natural preservation system that helped retain the bone's fine details. This discovery is considered one of the most exceptional cases of fossil preservation and provides new insights into the life of flying reptiles during the dinosaur era.
