325-Million-Year-Old Shark Fossils?!

Imagine stumbling on shark fossils that are older than dinosaurs—like, 325 million years old! That’s what scientists just found deep inside Kentucky’s Mammoth Cave. These ancient sharks, Troglocladodus trimblei and Glikmanius careforum, were about the size of today’s oceanic white tips. The wildest part? Their cartilage usually vanishes over time, but these were perfectly preserved in limestone. It’s like nature’s time capsule! This discovery is helping scientists piece together how sharks survived wild changes way before humans ever showed up. #Science #FossilFind #SharkWeek
