Remains of a new species of dinosaur that died ‘trekking through the desert with its two children’ 110 million years ago have been discovered in Argentina;
This new species was longer than a blue whale and weighed up to 120 tons, the remains of Lavocatisaurus agrioensis [amazes me why they don’t name them in a language, everyone can understand] came from three separate dinosaurs, which were a group of two juveniles and an adult , in an area of an arid plain with few natural water sources when they died…
The remains of a newly discovered species of dinosaur have been uncovered in Argentina, the new species walked the Earth 110 million years ago and was longer than a blue whale, weighing up to 120 tons, -the remains came from three separate dinosaurs from the herbivorous group of sauropods, the best known of which are the Diplodocus and Brontosaurus.
This new species has been named Lavocatisaurus agrioensis.
We found most of the cranial bones: The snout, the jaws, a lot of teeth, also the bones that define the eye sockets,’ said Dr Jose Luis Carballido, a researcher at the Egidio Feruglio museum, we were able to create an almost complete reconstruction.’
Parts of the neck, tail and back were also found, not only is this the discovery of a new species in an area where you wouldn’t expect to find fossils, but the skull is almost complete,’ added Dr Carballido.e dinosaurs moved around in a group and died together.
‘This discovery of an adult and two juveniles also signifies the first record of a group displacement among the rebbachisaurus dinosaurs,’ said study lead author Jose Ignacio Canudo of Zaragoza University.
The area in which the fossils were found is unusual for dinosaurs as it would have been a desert with sporadic lakes in that era, Sauropods were the biggest creatures ever to walk the planet, It is believed that Supersaurus could reach up to 34 meters (111 feet) in length and Argentinosaurus might have weighed up to 120 tons.
They were herbivorous quadrupeds with long necks and tails, massive bodies and small heads.
But the discovery in Neuquen, published in the scientific journal Acta Palaeontologica Polonica, remains a huge surprise, ‘While one can imagine that this group of sauropods could have adapted to move in more arid environments, with little vegetation, little humidity and little water, it’s an area in which you wouldn’t be looking for fossils,’ said Dr Carballido.
WHAT ARE SAUROPODS?
Sauropods were the first successful group of herbivorous dinosaurs, dominating most terrestrial ecosystems for more than 140 million years, from the Late Triassic to Late Cretaceous period, they had long necks and tails and relatively small skulls and brains.
They stretched to 130 feet (40 metres) and weighed up to 80 tonnes (80,000kg) – 14 times the weight of an African elephant, They were widespread – their remains have been found on all the continents except Antarctica.
They had nostrils high up on their skulls – rather than being located at the end of the snout like those of so many other terrestrial vertebrates.
Some fossils shows that these nostril openings were so far up the skull that there were very close to the eye openings.
Sauropods such as the Diplodocus began to diversify in the Middle Jurassic about 180 million years ago.
