Buenos Aires, Argentina:
Scientists have unearthed huge, 98-million-year-old fossils in southwest Argentina they are saying could have belonged to the most important dinosaur ever found.
Human-sized items of fossilized bone belonging to the large sauropod look like 10-20 p.c bigger than these attributed to Patagotitan mayorum, the largest dinosaur ever recognized, in keeping with an announcement Wednesday from the National University of La Matanza’s CTYS scientific company.
Sauropods have been huge long-necked, long-tailed, plant-eating dinosaurs — the most important terrestrial creatures to ever have lived.
Among them, Patagotitan mayorum, additionally from Argentina, weighed in at about 70 tonnes and was 40 meters (131 ft) lengthy, or concerning the size of 4 college buses.
Alejandro Otero of Argentina’s Museo de La Plata is engaged on piecing collectively a likeness of the brand new dinosaur from two-dozen vertebrae and bits of pelvic bone uncovered up to now.
He has revealed a paper on the unidentified dinosaur for the scientific journal Cretaceous Research, in keeping with the college assertion.
The quest for extra physique elements, buried deep in rock, continues. For scientists, the holy grail would be the massive femur or humerus bones, that are useful in estimating a long-extinct creature’s physique mass.
The huge fossils have been found in 2012 within the Neuquen River Valley, however excavation work solely started in 2015, in keeping with palaeontologist Jose Luis Carballido of the Museo Egidio Feruglio.
“We have more than half the tail, a lot of hip bones,” mentioned Carballido, who additionally labored on the classification of Patagotitan just a few years in the past. “It’s obviously still inside the rock, so we have a few more years of digging ahead of us.”
The huge skeleton was present in a layer of rock dated to some 98 million years in the past throughout the Upper Cretaceous interval, added geologist Alberto Garrido, director of the Museum of Natural Sciences of Zapala.
“We suspect that the specimen may be complete or almost complete,” he mentioned. “Everything depends on what happens with the excavations. But regardless of whether it is bigger (than Patagotitan) or not, the discovery of an intact dinosaur of such dimensions is a novelty.”
