Brontosaurus
"Brontosaurus" was a large, long-necked quadrupedal animal with a long, whip-like tail, and forelimbs that were slightly shorter than its hindlimbs. The largest species, "B. excelsus", weighed up to and measured up to long from head to tail. For comparison, the current largest land animal, the average male African bush elephant is 3.20 m (10.5 ft) tall at the shoulder and has a body mass of 6,000 kg (13,228 lb) or 6.6 short tons.
Bruhathkayosaurus
Bruhathkayosaurus (; meaning "huge bodied lizard") is a dinosaur, with remains found in India, claimed by some researchers to have been the largest dinosaur that ever lived. Estimates of size exceed the titanosaur "Argentinosaurus", as longer than and weighing over 80-200 tons. The accuracy of this claim, however, has been mired in controversy and debate. All the estimates are based on Yadagiri and Ayyasami's 1989 paper, which announced the find (see below: Size estimates).
