DinoStoreus - Amargasaurus Dinosaur Facts

Amargasaurus (ah-mar-ga-sore-us) meaning "Lizard from La Amarga," named after a canyon in Argentina where the dinosaur was discovered, lived during the Early Cretaceous period, approximately 131-125 million years ago. A smaller-sized sauropod, Amargasaurus was about 30-40 feet long, 13 feet tall and weighed about 5 ½ tons. As with all sauropods, Amargasaurus walked on all four legs, had a small head, a long neck, a long tail, and dined on the abundant forest vegetation, most likely conifers and ferns. But what makes Amargasaurus unique is its two rows of elongated spines growing from its backbone along its neck, back and tail. The function of the spines is unknown, and perhaps may have been covered with skin forming two sails. Found in Argentina, South America.
