Enormous dinosaurs are the hallmark of many visions of prehistory, but fossil evidence for these giants has been limited to the New World and Africa. Royo-Torres et al. (p. 1925) now describe a specimen of a huge dinosaur (40 to 48 metric tons) recovered from Upper Jurassic to Lower Cretaceous rocks in Spain. The specimen represents a new clade of sauropods that seems to have distinctly more primitive limb and bone structure than other giant sauropods found on other continents in Jurassic and Cretaceous rocks. Thus, enormous size arose in other groups of dinosaurs aside from the neosauropods.
