An international team of researchers discovered a new species of ichthyosaur, a marine reptile that lived in the age of dinosaurs.
"Whereas other ichthyosaurs had small, equally sized teeth for feeding on small prey, this new species modified its tooth sizes and spacing to build an arsenal of teeth for dispatching large prey, like big fishes and other marine reptiles," Hans Larsson, director of the Redpath Museum, said in a McGill University statement on Monday.
