is a genus of titanosaurian
dinosaur that lived in South America
towards the end of the Early Cretaceous. Titanosaurs are often known
by only a handful of fossils, but Patagotitan has
proved to be an
exception. At the time of writing Patagotitan is
known from the
partial post cranial remains of at least six individuals, and these
include remains of vertebrae (neck, back and tail), ribs,
shoulders, front and back limbs. The large size of these bones has
led to some crediting Patagotitan as the largest
dinosaur ever, but
this statement is highly speculative. The original describers
estimated Patagotitan to have grown to about
though others have suggested less, and others more. Future
discoveries and studies may well lead to further revisions.
