Horned, Spiked, and Crested Dinosaurs

By Carl Mehling

Some dinosaurs--with ten-inch thick skulls like the Pachycephalosaurus--were built to fight. This enchanting book takes readers on a journey into the world of dinosaurs whose horned, spiked, or crested features have created a wonderful dialogue about how these features evolved and were used for survival.
