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.

During the time of the dinosaurs, there were at least two crocs that grew to monstrous sizes worthy of a B-grade horror movie. Sarcosuchus, a roughly 110-million-year-old reptile, reached lengths of about 40 feet. Its narrow snout hints that it ate fish and relatively small fare. Another predator rivaled it in size: Deinosuchus, a roughly 40-foot-long creature that lived 80 to 73 million years ago and was a cousin of modern alligators. From tooth-marked remains, we know that this ambush predator ate dinosaurs.

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.
