Top 10 Largest Dinosaurs (to date)
Newly discovered dinosaur fossils, plus a new assessment of dino size, have led to a revised list of the top 10 largest dinosaurs to date.
The top 10 largest terrestrial animals on Earth were all dinosaurs, and a new analysis of dinosaur fossils reveals the biggest of the big.
Weighing in at No. 9 is Giraffatitan brancai. Its mass was calculated to be 37.5 tons.
No. 8 on the list is Futalognkosaurus dukei, which had an estimated mass of 42 tons. That’s equivalent to 84,000 pounds.
Next in the lineup is Elaltitan lilloi. According to the new study, its mass was 47.2 tons. This dinosaur lived in what is now southern Argentina.
Turiasaurus riodevensis is one of the largest dinosaurs ever to be found in Europe. The dinosaur, which had a mass of 56.1 tons, was excavated in what are now eastern Spain and Portugal.
Weighing in at 62 tons is Brachiosaurus altithorax, which was hailed as “the largest-known dinosaur” by discoverer Elmer Riggs in 1903. While it’s No. 5 on the list now, at 62 tons, this dinosaur still made the top 10.
Sauroposeidon proteles was not included in the Scientific Reports study. This species, and the entire genus, are only known from several incomplete specimens. So it’s more challenging to accurately estimate its weight and height. Some paleontologists theorize that it weighed anywhere from 55-66 tons. It could, therefore, move even higher on this list should more fossils be found.
Lacovara and a team of his colleagues discovered Paralititan stromeri in 2001. “We only recovered the humerus of Paralititan, and therefore cannot be sure about its limb proportions,” Lacovara told Discovery News.
“Dreadnoughtus schrani has the largest reliably calculable weight of any known land animal,” Lacovara said. Announcement of its discovery was made just this week, reminding that on any day, new fossil finds could change this list.
Most paleontologists, including Lacovara, believe that Argentinosaurus huinculensis was the world’s largest-ever land animal. “I think it is very likely that Argentinosaurus is the most massive dinosaur yet known,” Lacovara said. “However, I don’t think we can make a reliable estimation of its mass.”
