The Prehistoric Giants Hall of Fame
What were the largest species of all time? Does the Tyrannosaurus rex make the list?

Titanoboa was one gigantic snake. It lived around 58 to 60 million years ago, a scant several million years after the mass extinction that wiped out the dinosaurs. It could grow 42 feet or more in length and weigh more than a ton, vastly outslithering the previous fossil record holder, a 40-million-year-old, 33-foot-long snake called Gigantophis. But Titanoboa is just one proud inductee in the Prehistoric Giants Hall of Fame. Meet the other record-holders.

Tyrannosaurus rex may be the king of the predatory dinosaurs in pop culture, but the 42-foot-long carnivore may not have been the largest. The sail-backed Spinosaurus from the Cretaceous Period might have been the longest of the predatory dinosaurs. Although no complete skeleton has been found, estimates place this bruiser at between 41 and 59 feet long.
And among the theropods, Giganotosaurus from South America and Carcharodontosaurus from the Sahara have given Tyrannosaurus some close competition. Both of these knife-toothed dinosaurs were about 40 to 43 feet long. The competition in this group is currently too close to call.

What, no largest lizard ever? How could you pass over Megalania Prisca, all 20 foot + and 2000 lbs. + of it?

Do any of these exceed the largest mammal? Are there any fossils of mammals bigger than the Great Blue Whale?

Size is irrelevant. The most fascinating critter is the tiny jellyfish that regenerates itself.(turntopsis nutricula)?

Dude! How can you possibly not have a category for the biggest flying animal ever? Azhdarchid pterosaurs like Quetzalcoatlus and Hatzegopteryx dwarf the puny Argentavis and more interesting than just a bigger buzzard. It's not like these pterosaurs are so well-known that they might be left out (like the blue whale) as being universally known. Sigh. Still, any excuse to haul out some very nice paleoart, so thanks for that.
