Previously unknown dinosaur species have been discovered by researchers in southern Argentina. Paleontologists from Spain and Argentina, found in the vicinity of the Andes, bones of an animal twelve meters long and two of the smallest specimens.
The plant eaters lived 110 million years ago in a desert territory of the present province of Neuquén. Their best known parents, also herbivores, are the representatives of the genus Brontosaurus. The newly discovered species has received the name of Lavocatisaurus agrioensis.
almost complete skull bone
"We found most of the bones of the skull and a large number of teeth that were restored quite completely," said José Luis Carballido of the Egidio Feruglio Museum, in the town of Trelew in Patagonia. The researchers also discovered the bones of the neck, back and tail.
Work in the vicinity of the Andes
You have not found the new way only in an area where you necessarily expect fossils, but also an almost complete skull bone, according to the researchers. Their results were published in the journal "Acta palaeonto Logica Polonica".
Dinosaurs probably lived in herds
In addition to the adult animal, the researchers also discovered the remains of two more recent specimens six to seven meters long. According to the researchers, the dinosaur died in a group on the road and together.
The area in which the fossils were found is however unusual for dinosaurs. It was an old region in the desert with only a few lakes in the area of the discovery site.
The sauropods, including one of the newly discovered species, are the greatest creatures of all time. The researchers assume that it could be more than 30 meters long. Species of the genus Argentino saurus have probably reached a weight of 70 tonnes. Characterized by long necks and tails, a massive body and a relatively small head.
You can imagine, although the giants have traveled the barren and water-poor region, according to the researchers. Had suspected animals there, but not necessarily.
