How well do you know SUE?

The towering Tyrannosaurus rex that greets visitors at The Field Museum is hard to miss. But how well do you really know SUE? To celebrate SUE’s Unearth Day on August 12, the date she was discovered, we’re brushing up on some essential facts: Who is SUE? Even though we refer to SUE as a “she,” it is unknown whether this T. rex was female or male. We know that this carnivorous dinosaur lived about 67 million years ago and probably weighed nine tons during its life.

Newly-discovered dinosaur had “T. rex arms” that evolved independently

Scientists still aren’t sure why T. rex had those absurdly small forelimbs, but apparently the look was all the rage in the Late Cretaceous. A newly-discovered dinosaur from Patagonia has similar short, two-fingered claws, even though it’s not closely related to the tyrannosaurs.

Revisiting “Jurassic Park”: Could dinosaurs really be cloned?

“Where do you get 100-million-year-old dinosaur blood?” asks Dr. Ellie Sattler, a character in the original “Jurassic Park” movie. In the film, dinosaurs are cloned from DNA preserved in amber. More specifically, from dinosaur blood inside mosquitoes that are trapped in the amber. Spoiler alert: things get a little out of hand as the cloned dinos wreak havoc on Isla Nublar.
