Futalognkosaurus

Futalognkosaurus ( ; meaning "giant chief lizard") is a genus of titanosauriandinosaur. The herbivorousFutalognkosaurus lived approximately 93.5 to 85.8 million years ago in the Portezuelo Formation, in what is now Argentina, of the Coniacian stage of the late Cretaceous Period. The fish and fossilized leaf debris on the site, together with other dinosaur remains, suggest a warm tropical climate in Patagonia during this period.
