Dinosaurs remain to be one of the greatest mysteries left for us to figure out. The fossils that they leave behind have managed to answer a lot of our questions, but we are still left with the question of what made them extinct. I like how this book provided insight to how much we can figure out just by studying fossils, but it still leaves the open ended question to as what happened to all of these creates? I think they book could have provided technical names of diets of animals. Rather than calling them meat-eaters or plant-eaters, i think the readers could have handles learning about carnivore, herbivore, and omnivores. ( )
