Source!2: How Dinosaurs Survived Dinosaurs lived millions of years ago during the Jurassic period. Some dinosaurs were carnivores, or meat-eaters, and others were herbivores, or plant-eaters. Structural adaptations are physical features animals have that help them survive. Each type of dinosaur had different structural adaptations that made it easier for them to get their food. Carnivorous dinosaurs had adaptations to help them catch and consume their prey. One of those adaptations was large, sharp teeth and claws. Their teeth helped them kill their prey and easily bite into the meat. The sharp claws allowed the dinosaurs to catch and kill prey as well. Meat-eating dinosaurs also had strong jaw muscles and thick jawbones. That made using their pointed teeth more efficient. Another adaptation these dinosaurs had was speed. Most carnivorous dinosaurs were relatively fast, and being able to move around quickly made it easier for them to catch their prey. Herbivorous dinosaurs, on the other hand, had adaptations that made eating plants easier. The stegosaurus is an example of a herbivorous dinosaur. The stegosaurus walked on all four feet, and its back legs were longer than its front legs. As a result, its head drooped low to the ground. Stegosauruses ate the ferns and other plants that grew low to the ground. Plant-eating dinosaurs had flat teeth, instead of sharp teeth like the meat-eaters. Flat teeth were needed to grind the plants up. Plant-eaters didn’t need to kill and bite prey with sharp teeth. Instead, they needed to grind and mash up their leaves. To protect it from the meat-eaters, herbivores usually had plates on their backs. The plates acted like armor that protected the herbivores from the sharp teeth of the meat-eaters. Those are some adaptations herbivorous dinosaurs used to survive. Even though they lived so long ago, dinosaurs adapted to their environment. Their teeth, claws, coverings, and limbs helped them survive. #$!%&'()*!+,-.!
