The Sauropodomorpha was a diverse group of (generally) large animals with long necks and tails. This group contains the largest dinosaurs that ever existed! Some could grow over 40 m in length and weighted over 100.000 kg! They evolved during the Late Triassic, thrived during the Jurassic and finally went extinct during the K-Pg event at the end of the Cretaceous.
Distribution & Fossil evidence
Sauropods lived all over the world and fossils are known from every continent, even Antarctica. The Sauropods evolved during the Late Triassic from small, two-legged dinosaurs. The oldest members are known from Argentina and grew up to 1.3 m in length.
There are many genuses and species known within the Sauropodomorpha clade. A few famous species are the Brachiosaurus, Argentinosaurus and Diplododus.
