Crack open any science textbook and the authors will tell you that such things don't happen. So how did a couple of paleontologists and an acid bath turn that widespread belief on its head?

Birds then dinosaurs or dinosaurs then birds? It's a lot like the chicken-and-egg question, only with paleontologists. Who's arguing what these days, and what are they citing as evidence?

Researchers think the Chicxulub crater was caused by the massive asteroid that also killed off the dinosaurs 66 million years ago. What else do we know about this peak-ring crater?

When they discover dinosaur remains, how do scientists know whether they found a male or a female? Would you believe it all comes down to one bone?

Fossils tell a story, much like the clues at the scene of a crime. Researchers look for evidence and paleontologists study that evidence to answer questions about the past.

Anthropologists specialize in, well, us. But studying humankind doesn't mean you have to hole up in a library or laboratory. Take a peek at this article to learn more about the dynamic, enriching field of anthropology.

At best, fossilization is a long and tricky process that mineralizes an occasional Tyrannosaurus rex or other extraordinary find. How has that affected our chances at charting a model of life itself?

It's easy to trace the evolution of the automobile. Your family tree poses a whole different challenge. Even an extensive genealogy chart can only reach back so far. So how do we chart the evolution of the human race?

You likely heard that paleontologists uncovered a cache of dinosaur embryos, bone fragments and eggshells in China. You also may recall that we've made crazy leaps forward in genetics and genomics. Can we put the two together and create a dinosaur?

The 1993 movie "Jurassic Park" did a good job of bringing the idea of cloning dinosaurs into popular culture. It portrayed dinosaur cloning in a way that made sense to a lot of people, but is it really possible?
