Its name translates to “a giant thunderclap at dawn” — and it’s easy to see why.

Some 200 million eld ago , a 12 - ton dinosaur that was double the size of it of an African elephant stomped around South Africa .
In a study just publish inCurrent Biology , a team of researcher expose that a recently unearthed fossil run them to the discovery of a fresh dinosaur species that they ’ve namedLedumahadi mafube .

The dinosaur ’s name translates to “ a gargantuan thunderclap at sunrise ” in Sesotho , a South African language spoken in the region where the dinosaur ’s bone was constitute .
The Jurassic - era creature , which was a close relative of the brontosaurus , was monumental . The researchers believe that it weighed 26,000 pound and was the orotund state fauna of its metre . The animal ’s discovery is groundbreaking not only because of its size but because of the insight it has feed scientist into the evolution of its later relatives .
According toCNN , Blair McPhee , a grad educatee and paleontologist , key the dinosaur ’s bone back in 2012 . They did n’t know what species of dinosaur the bones belonged to and the rest of the bones were still in rocks in the field , make believe archeological site a painstaking process .

“ It take up a long time because the deposit they were encase in had basically turned to concrete over about 200 million years , and it was sort of on a thin drop face , ” McPhee explained toNPR .

After years of excavating , the team removed the finger cymbals , studied them and made their startling find : a new dinosaur . They conclude that the dinosaur was a fully - acquire grownup and had been around 14 years onetime when it fail .

TheLedumahadi mafubewas an former ancestor of the sauropod dinosaur , which were a group of large herbivores , like the apatosaur , that walked on all four leg . However , the researcher believe that theLedumahadi mafubeitself evolved from smaller ascendant who got around on two branch .
This fact caused researchers to judge theLedumahadias a transitional dinosaur , imply it was a kind of evolutionary experimentation that was a compounding of different traits .
“ The first thing that struck me about this animal is the incredible robustness of the limb bones , ” McPhee said harmonize toScience Daily . “ It was of a similar sizing to the gigantic sauropod dinosaur dinosaur , but whereas the arm and legs of those animals are typically quite sylphlike , Ledumahadi‘s are incredibly thick . ”
The researcher developed a method of examination to see if this giant dinosaur walked on two peg or four . To do so , they gathered entropy on leg size and thickness fordinosaurs , beast , and reptiles that take the air on either two or four leg .
They then compare that information against the datum collected from theLedumahadifossil and concluded that the animal walked predominantly on four leg but could have popped up onto two leg to strive things on gamy branches .

According toNPR , this evolutionary adjustment permit the massive dinosaur to possess remarkable stability and may have help its later descendants like the brontosaurus to acquire to monolithic sizes .
what is more , the discovery of theLedumahadihas also sparkle raw insight into the geographics of prehistorical Earth . Because theLedumahadiwas also related to large dinosaurs that lived around the same time in Argentina , the researchers believe that this supports the possibility of the supercontinent Pangea .
“ It shows how well dinosaurs could have walked from Johannesburg to Buenos Aires at that time , ” Jonah Choiniere , an source of the study and a paleontology professor at the University of Witwatersrand in Johannesburg .
Indeed , the massiveLedumahadimay very well continue to upend much of what we only think we recognise about Earth in the old age of the dinosaur .
