Saltasaurus

&nbsp Saltasaurus was a Medium sized (by Sauropod standards), herbivorous dinosaur that lived in the Cretaceous period. It belonged to the group of sauropods called the Titanosaurs. Saltasaurus was discovered in the salt plains of argentina (hence the name). It is instantly recognisable because of the hard circular armour that covered this dinosaur's trunk (middle part of the body; back, sides and start of tail) and tail. these are thought to have protected it from harm from the Abelisaurids that hunted Argentina at the time.
