The 98 million - year - sometime remains of what might be the largest animal to take the air Earth — a long - make out titanosaurian dinosaur — were recently unearthed in Argentina .
The remains of the unnameddinosaurwere first discovered in 2012 in Neuquén Province of northwest Patagonia , but have still not been amply excavate . However , the os that have been unearthed so far suggest the ancient colossus was potential a titanosaurian , possibly the largest one on record . titanosaur were amongst the largest sauropods — long - neck , plant - eat giant dinos — and endure from the lateJurassic period(163.5 million to 145 million old age ago ) to the closing of theCretaceous period(145 million to 66 million years ago ) .

" Given the measurements of the new skeleton in the closet , it look likely that this is a competition for one of the largest , if not the big , sauropods that have ever been found , " Paul Barrett , a paleobiologist at the Natural History Museum in London who was not involved in the cogitation , told Live Science .

Not enough of the stiff have been uncovered for the investigator to declare this dinosaur as a fresh species or attribute it to an already known one . However , the researchers are surefooted that once the mining is complete , they ’ll be capable to classify it as a completely fresh species .
Researchers uncover parts of the titanosaur at the excavation site in Neuquén province, Argentina.
" The place of the determination is very heavy to access , so the logistics is pretty complicated , " lead bailiwick author Alejandro Otero , a paleontologist at La Plata Museum in Argentina , told Live Science . " But we look to return there after thepandemicsituation . "
The remains themselves escort to about 98 million years ago , meaning the puppet lived during the Cretaceous period .
A giant among giants
In 1993 , another titanosaur calledArgentinosaurus huinculensisclaimed the claim of largest land - based dino , but was by and by superceded by the even big titanosaurPatagotitan mayorumin 2014 . However , it ’s challenge to specify which species was the heaviest dinosaur — Argentinosaurusis known from just 13 fossilised bone , andPatagotitan’sweight was found on a composite of six individuals , Live Science previously describe .
Right now , the researchers ca n’t say how big the new titanosaur was , given that the long arm ivory used to make such estimates , such as the humerus and femur , have not yet been excavate . However , analysis of the bones that have been come up — including 24 vertebra of the tail end and part of the pelvic and pectoral stays — show that it was most likely the largest of the titanosaur .
" The specimen is considered one of the largest sauropods ever found , probably exceedingPatagotitanin sizing , " the researchers write .
The titanosaur excavation is not yet complete.
Patagotitanwas approximately 50 ft ( 15 meters ) tall and weighed 69 gross ton ( 62 metrical tons ) , which is tantamount to the system of weights of nearly a twelve Asiatic elephants .
" It is a huge dinosaur , but we expect to observe much more of the skeleton in next field slip , so we ’ll have the possibility to address with confidence how big it really was , " Otero said .
The fresh discovered titanosaurian is just one of many sauropod fossils uncovered in South America , includingDreadnoughtusandSarmientosaurus .

These have helped to fill up in multiple knowledge gaps circumvent these giants and also leaven interrogative about how they grow so full-grown .
" This novel skeleton provide yet another exemplar of sauropods pushing at the extremum of what ’s possible with respect to maximum animal size on state , " Barrett said .
The report was publish online Jan. 12 in the journalCretaceous Research .
in the beginning published on Live Science .
