|Life restoration of Camarasaurus lentus by Christopher DiPiazza.|
The name, Camarasaurus translates to "chambered reptile" because of the hollow spaces within its vertebrae. This is a feature common to many dinosaurs which allows the animal to be large but not too heavy. Some dinosaurs (the birds) even utilized this adaptation to fly.

Unlike some other sauropods, like Apatosaurus and Barosaurus, which had shorter front limbs than hind limbs, or Brachiosaurus which had longer front limbs than hind limbs, the front and back limbs of Camarasaurus were relatively equal in length. Camarasaurus also had a much shorter snout than many other sauropods, giving its head a very distinctive boxy look. Many Camarasaurus specimens have been discovered including some nearly complete skeletons. There have even been multiple skeletons including adults and juveniles discovered in close proximity to each other which suggests that these dinosaurs probably lived in groups.
