Scientists Discover 310-Million-Years-Old Nursery of Bandringa Sharks
The long-snouted Bandringa shark (Elasmobranchii, Chondrichthyes) – a bottom-feeding predator that lived in an ancient river delta system in what is today the Upper Midwest – is likely one of the earliest close relatives of modern sharks.
It resembled present-day sawfish and paddlefish, with a spoon-billed snout up to half its body length. Juveniles were 4 to 6 inches long and grew into adults of up to 10 feet.
