At 70 feet long, Alamosaurus was the largest animal to roam the American west in the Late Cretaceous. These huge dinosaurs were among the last of the great line of sauropods (long-necked dinosaurs) that had flourished in the Jurassic and Early Cretaceous. This animal's size was a tremendous advandtage when it came to defense, even rendering it nearly immune from the mighty Tyrannosaurus. Shown here are an adult and a juvenile. #alamosaurus #animal #birdman #cretaceous #dinosaur #prehistoric #sauropod #texas #titanosaur
