GENERAL GEOLOGY

Detailed explanation-1: -The heaviest dinosaur was Argentinosaurus at 77 tonnes. It was the equivalent to 17 African Elephants. Argentinosaurus is a double award winner being also the longest dinosaur. It is also the largest land animal to have ever lived.

Detailed explanation-2: -Although it is only known from fragmentary remains, Argentinosaurus is one of the largest known land animals of all time, perhaps the largest, reaching 30–35 metres (98–115 ft) in length and 60–75 tonnes (66–83 short tons) in body mass.

Detailed explanation-3: -The discovery of such a large femur allowed many paleontologists to assert that Paralititan rivaled Argentinosaurus in size. Estimates of the titanosaur’s length and weight vary: length estimates range from 25 to 30.5 meters (82 to 100 feet), and weight estimates range from 60 to 75 metric tons (about 66 to 83 tons).

Detailed explanation-4: -Bruhathkayosaurus, a dinosaur that may have been as big or even bigger than Argentinosaurus, was only known from limb, hip, and tail elements, and those fossils disappeared (much like the near-mythical dinosaur giant Amphicoelias, estimated to be 190 feet long from a long-lost piece of vertebra).
