These basic elements are ancient and their proportions maintained over vast differences in body size. Both enormous sauropod dinosaurs and small, delicate salamanders from the Jurassic age (over 150 million years ago) display the same repeating molecular architecture of the vertebrate body plan." https://padlet.com/gweiss1/efmb1/wish/2906781544 Top of page 21
