Facts About Dinosaurs

How do scientists know whether dinosaur fossils are male or female?

One of the most complete Tyrannosaurus rex fossils in the world is named Sue. But no one really knows whether Sue is a boy or a girl -- the fossil got its name from the paleontologist who found it. As it turns out, figuring out the sex of a dinosaur is harder than it sounds, since the relevant parts of the body are all gone by the time someone finds the bones. But a few scientists have succeeded.

Can scientists clone dinosaurs?

If you believe what you see in the Jurassic Park movies and books, cloning dinosaurs is as easy as taking blood from a mosquito and mixing it with DNA from a frog. But reconstructing dinosaur DNA is more like building a ladder to the moon with only enough rungs to reach the top of your house. And it turns out that birds might be a better match for dino DNA than frogs. With recent discoveries of dinosaur mummies and soft tissue in fossils, has it become more likely that scientists could create a dinosaur clone?

Could dinosaurs swim?

Most cats don't swim by choice. But if one falls into the water, it can usually swim well enough to try to make its way out again, which is also the case for many other animals. Did this rule of thumb hold true for dinosaurs, or did some steer clear of water at all costs? Finding the answer is easier said than done — there aren't any eyewitnesses, and swimming dinosaurs didn't leave much evidence behind. But researchers have found a few clues about whether dinosaurs took to the water.
