Resumen:
A unique site at the northern area of Patagonia (Neuquén, Argentina) reveals an Upper Cretaceous ecosystem in a detail never reported before. An extraordinary diversity and abundance of fossils was found concentrated in a 0.5 meter horizon in the same quarry, including a new titanosaur sauropod, Futalognkosaurus dukei n.gen., n.sp, which is the most complete giant dinosaur known so far. Several plant leaves, showing a predominance of angiosperms over gymnosperms that likely constituted the diet of F. dukei were found too. Other dinosaurs (sauropods, theropods, ornithopods), crocodylomorphs, pterosaurs, and fishes were also discovered, allowing a partial reconstruction of this Gondwanan continental ecosystem.
