Mesetasaurus is a titanosaurian sauropod dinosaur that lived during the Late Cretaceous period in what is now Uruguay. Like all sauropods, it stood on four pillar-like legs, using its long neck to reach the vegetation it fed on, counterbalanced by its long tail. Relatively small for a titanosaur, Mesetasaurus grew to approximately 10 m in length. © TotalDino · CC BY 4.0 · Wikimedia
