what was the heaviest dinosaur

According to the search results, the heaviest dinosaur was Argentinosaurus huinculensis, a titanosaur that lived in what is now South America roughly 97-93.5 million years ago during the Late Cretaceous period. It is estimated to have weighed somewhere between 60 and 124 tonnes, with most paleontologists favoring the lower reaches of this range (between 60 and 90 tonnes) . Its weight was equivalent to 17 African elephants. Other titanosaurs, such as Patagotitan and "Antarctosaurus" giganteus, were also among the largest and heaviest dinosaurs.
