Scientists said some of the most mysterious and frightening creatures in the oceans today were swimming all over Kentucky 350 million years ago.
“There was no cave here,” said paleontologist JP Hodnett. “It was just a big open marine ocean floor with lots of water over your head. Over time that filled up and then it became dry land.”
Learning that sharks lived in our backyards all started by chance at Mammoth Cave. Back in the 90s, guides started noticing shark teeth and other fossils. But no one had ever found any shark fossils from this layer until now.
