👉 The Aigialosaurus is a genus of sauropod dinosaur that lived during the Late Cretaceous period (around 104 to 63 million years ago), and was found in South America. Its name comes from the Latin word for 'lizard', as it had elongated limbs and a lizard-like shape. The genus Aigialosaurus is believed to be a member of the Sauropodomorpha group, which includes several other sauropods like the Brontosaurus and the Velociraptor.
