ORTHACANTHUS:
260 million years ago, Orthacanthus was the terror of freshwater swamps and bayous in Europe and North America. It had an eel-like body that is believed to have reached nearly 10 feet in length. Its powerful jaws were lined with double-fanged teeth. This shark belongs to a group of very successful sharks that lived mainly in fresh waters. This group of sharks first appeared almost 400 million years ago, and became extinct just before the time of the dinosaurs, approximately 225 million years ago.
