WASHINGTON — A 300 million- year-old fossilized brain has been discovered by researchers studying a type of fish that once lived in what is now Kansas and Oklahoma.
“Fossilized brains are unusual, and this is, by far, the oldest known example,” said John Maisey, curator in the division of paleontology at the American Museum of Natural History in New York.
Maisey and co-authors report in the online edition of Proceedings of the National Academy of Science that the brain was discovered in a fossilized iniopterygian, an extinct relative of modern ratfishes, also known as ghost sharks.
