B. Rex: Giant Armored Fish Was King Before Dinosaurs

A team of scientists discovered the fossils of Bothriolepis rex, a new giant in the group Antiarchi — ancient fish with armored plates covering their head, shoulders and front fins. "Bothriolepis rex extends the range of known body sizes for the group Antiarchi," Jason Downs, a research associate at the Academy of Natural Sciences of Drexel University, in Philadelphia, and an assistant professor at Delaware Valley University in Doylestown, Pennsylvania, said in a statement.
