The king is dead! Long live the king!

When it was discovered over 100 years ago, North America's Tyrannosaurus rex was the largest meat-eating dinosaur known. Scientists dubbed it the "tyrant lizard king."

In 1995 a new species, Gigantosaurus, was discovered in South America. At 47 feet in length, it nosed out 45-foot long T. rex as the biggest dino carnivore.

But now a new champion has been crowned. A Spinosaurus from North Africa is estimated to be 55 feet long! (All that exists of this skeleton is the skull. But, by comparing this new, larger skull to those on more complete Spinosaurus fossils, scientists can estimate the length of the total creature.)

Spinosaurus was originally discovered in 1915, and even then some scientists thought it might be bigger than T. rex. But the Spinosaurus fossils were destroyed during World War II. The new skull puts to rest any doubt -- Spinosaurus is the largest meat-eater known to science.

(The largest dinosaur of all is Argentinasaurus, a plant-eater from South America.)

The post was created three years ago. At that time, the Spinosaurus was indeed the largest meat-eating dinosaur known. We were not late, and we were not incorrect.

You also don't mention which dinosaurs are bigger, so I'm not sure if you're talking just about meat-eaters, as the post does, or whether you include plant-eaters as well.

Well, someone was late, anyway.

Also... I'm pretty sure spinosaurus is still the biggest (longest?) carnivorous dino on the books. About 30 seconds of googling would probably clear this up, but I'm feeling lazy. And I want to look smart. Isn't it, like... spinosaurus, giganotosaurus, carcodontasaurus (or something like that), and then T. rex?

If I'm wrong, don't hold it against me—it was just off the top of my head. But if I'm right... please give me props—it was just off the top of my head.
