Scottish 443-million-year-old eel-like fossils reveal early bones and camera-like eyes
Researchers using synchrotron X-ray imaging analyzed 443-million-year-old Jamoytius and Lasanius fossils found near Glasgow. They discovered bone-like tissues and traces of zinc and copper in the eyes, indicating advanced camera-type eyes and early bone development in vertebrates, pushing back the origin of these features. The study, published in Proceedings of the Royal Society B, suggests these early vertebrates were less primitive than previously thought.
