Animantarx

The Animantarx was an approximately 3-metre-long dinosaur with bone plate armour. Only one skeleton of the dinosaur has ever been found, so we don'™t really know so much about it. It lived during the Upper Cretaceous period, at the time of Argentinosaurus and Giganotosaurus, and fed on plants. Fun fact-The thick armour gave the Animantarx its name. Its name contains the Latin word arx, meaning fortress.
