A newly discovered tail vertebra of the Titanosaur Alamosaurus has shed new light on the unusual dinosaur, which is now though to have been one of the largest of all. The new bone is slightly larger than that of Futalogknosaurus, which is thought to be 30-32m in length. Alamosaurus was unusual because after the end of the Jurassic, the sauropods of North America declined, leaving none left by the end of the Early Cretaceous, all replaced by Ceratopsians and Hadrosaurids as large herbivores. However, with the rise of the Titanosaurids in the Southern Hemisphere came Alamosaurus, the only sauropod so far discovered in the Late Cretaceous of North America. Titanosaurids also reached Asia, Africa, Australia and South America. Alamosaurus lived at roughly the same time as Tyrannosaurus, and bite marks from the large (and hugely overrated) predator have been found of some of the titanosaurs' remians, dispelling Jack Horner's scavenger theory.
Personally I love this discovery as Alamosaurus is one of my favourite sauropods
