We learn a lot from dinosaurs. They could live to be 100 years old. First of all, dinosaurs are wonderfully diverse. Paleontologists have recognized over 1,000 distinct non-avian species, from tiny, feathery insect hunters to giants that grew to be over 100 feet long and weigh over 70 tons. To name a few, there were horned dinosaurs, armored dinosaurs, dome-headed dinosaurs, crested dinosaurs, long-necked dinosaurs, sickle-clawed dinosaurs and our favorite  (in our CynderRex Collection) - The Happy Dinosaur! RAWrrrrr!
