These wild details and more are packed into the new book "The Rise and Fall of the Dinosaurs: A New History of a Lost World" (William Morrow, 2018), which hits real and virtual bookstore shelves tomorrow (April 24).

The book is great for both casually interested readers and the most passionate dino lovers. It follows the paleo-beasts from their rise during the Triassic period about 240 million years ago to their sudden, catastrophic demise at the end of the Cretaceous, about 65.5 million years ago. Step into the world of the scientists who dig up fossils, and learn about the discoveries they've made, including how researchers first found fossilized dinosaur feathers, dug up dwarf dinosaurs and discovered the tyrant lizard king, T. rex.
