In 2015, scientists found 200-million-year-old fossil remains of a huge salamander-like amphibian, a "super salamander," that was a top predator of rivers and lakes. It might have even munched on early dinosaurs! Young paleozoologists will love learning about these remarkable creatures that once lived on Earth as well as seeing imaginative images of what they might have looked like. They’ll be amazed how such beasts change and adapt into the animals we know today.
