Largest Dinosaur in the world: Dinosaurs came in all shapes and sizes, but one stood above them all was Argentinosaurus. This titanosaur from South America holds the title of the largest dinosaur ever found. Though only partial fossils have been recovered, scientists estimate that Argentinosaurus was the heavyweight champion of the prehistoric world.

Which Is the Largest Dinosaur in the World?

The largest known dinosaur is Argentinosaurus huinculensis, a massive herbivorous sauropod that lived about 94 million years ago in what is now Argentina. This dinosaur was part of the titanosaur group, famous for their long necks, enormous bodies, and slow but steady movements.

How large was the dinosaur? 

The Argentinosaurus, a colossal titanosaur is estimated to have been an astonishingly large creature, though its exact dimensions remain somewhat speculative due to the absence of a complete skeleton. Based on fossilised vertebrae and leg bones, and by drawing comparisons with other titanosaurs, palaeontologists estimate its length to have been between 30 and 35 metres (98–115 feet). At the shoulder, its height is believed to have been around 7 metres (23 feet), a truly towering stature. Furthermore, this magnificent dinosaur is thought to have weighed an incredible 100 tonnes (220,000 pounds)

Was Argentinosaurus carnivorous or herbivorous?

It was herbivorous. Argentinosaurus fed on plants and used its long neck to reach treetops and cover large feeding areas.

Are the remains of Argentinosaurus preserved today?

Yes, but only partial remains have been found. These include 13 vertebrae, rib fragments, and part of a femur, preserved in museums and fossil labs in Argentina. No complete skeleton has ever been recovered.
