Researches say they have found the biggest dinosaur ever, in a desert
near La Patagonia, Argentina. They have found
fossilised bones of a dinosaur and they believe it has been the largest
creature ever to walk the Earth.
Based on the fact of its huge bones, it was 40m long and 20m tall. Researches measured the
diameter of load-bearing bones like the femur and humerus and they were able to
estimate the size and weight of the dinosaurs. This massive dinosaur was as heavy as 14
African elephants, 77 tones. It’s even seven tonnes heavier than the previous
dinosaur discovered, Argentinosaurus.
But this gigantic dinosaur was a herbivore. It
belonged to the sauropod group of dinasours, which are charasterised by their
small heads, thick, pillar-like legs, and long necks and tails. But this one,
is twice as long and four times as heavy. Researchers are even classifyng it as
a new species of Titanosaur !
Based on the age of the
rocks, researchers have conlcuded that this giant hervibore lived in Patagonia
forests abour 95 and 100 millions years ago.
They found about 150 bones in total all in "remarkable
condition". The dinasour fossils were excavated by a team of palaeotologists
, led by Dr Jose Luis Carballido and Dr Diego.
“Such dimensions put
the focus on the extent to which these animals may have grown. It's a real
paleontological treasure,"says José Luis Carballido
The dinosaurs were
found very close together along with a number of carnivorous dinosaurs. So,
basically it is believed that they may
have died during a drought. Researches suggest
it could be possible that they died of dehydration or became stuck in
the mud. Further
analysis of the suggests that the area was different to how it looks
today. Rather than a dry, arid land, it is likely that there were trees and and
a wide variety of plant-life.
