Though they are extinct for the past millions of years these huge dinosaurs survived among larger carnivorous dinosaurs and managed to survive in big numbers if the number of fossils recovered is any indication. However, scientists warn that the occurrence of a large number of fossils doesn’t really mean that they were present in large numbers.
Camarasaurus species roamed the semiarid lands of North America around 155 to 145 million years ago. Let us see some of the features that might have helped them survive.
(1) These dinosaurs belonged to those long-necked dinosaur groups that were living in those times. This could have helped them to eat from the top of the trees meaning that they had lesser competition from other animals. The long hind legs could have also helped the animal to reach the top of the trees by standing only on them.
(2) The vertebrae of the Camarasaurus has a lot of hollow chambers which gives it the name which means “hollowed lizard”. These had air sacs which were connected to the lungs which probably helped the huge animal breath more efficiently.
(3) The hollow chambers in the vertebrae could have also helped in reducing the weight of the animal. This must have helped in easy movement on considerably short legs. The front legs were shorter than the hind legs.
(4) This dinosaur had very strong and large teeth which could cut and chew even hard and coarse leaves which many of its cousins could not manage. This gave it the advantage of eating leaves that others avoided. It made finding food that much easier for the Camarasaurus.
(5) Another feature that helped the Camarasaurus live its life as an herbivore is that its teeth were replaced every 62 days. This helped in chewing a huge amount of coarse and hard leaves and plants.
