Feathered Dinos TOOB® - 681904

Recently, scientists have discovered that many dinosaurs were feathered! This toob includes a feathered psittacosaurus, protoceratops, pachycephalosaurus, chasmosaurus, apatosaurus, t-rex, caudipteryx, dilong, beipiaosaurus, microraptor, velociraptor and sinornithosaurus. History: The actual hypothesis that birds were descendants of dinosaurs was suggested as early as the mid-19th century by biologist Thomas Henry Huxley. However, without significant evidence, huxley's theory never gathered steam. Characteristics: although scientists aren't sure why dinosaurs evolved to have feathers, one thing that's certain is that they were not capable of flight like modern day birds. While there are many theories, such as heat regulation and defense tactics, perhaps you will be the one to finally solve the riddle with careful study of these accurately sculpted and researched figurines! Size: all 12 dinosaur figurines in this toob range from 1.25 to 3.75 inches tall.
