A team of scientists has discovered a “trove of fossil treasures” consisting of at least 40 different species of sharks in the past 10 months at Mammoth Cave National Park. Park officials said it is one of the most diverse Mississippian shark faunas in North America. The Paleozoic Era species are also referred to as “Mississippian” which is a term used by geologists in North America to describe the time period between 358.9 and 298.9 million years ago, according to the National Parks Service. Officials said the discovery includes six new species and rare preservations of three-dimensional skeletal cartilage.
