It's that time of year where we round up all our favorite science discoveries of the year, and today, we're talking fossils. From a wild mosasaur with screwdriver teeth, to glittery gold fossils, and even a mammal-versus-reptile fight to...

If you know one thing about pterosaurs, it’s that they’re flyers. And while pterosaurs may be well-known for their domination of the skies in the Mesozoic Era, they didn’t live their entire lives in the air. So how did we figure this...

The ecological niche of apex predators was empty on Hateg Island, waiting to be occupied by something large, mobile, and powerful enough to fill it.

When pterosaurs first took flight, you could say that it marked the beginning of the end for the winged reptiles. Because, strangely enough, the power of flight -- and the changes that it led to -- may have ultimately led to their downfall.

There’s a lot of confusion out there about what is and isn’t a dinosaur. And you’d be forgiven for being kinda confused. Maybe paleontologists are just messing with us. Or… maybe the question of what is and isn’t a dinosaur goes deeper...

The birds you see around today might not be that big, but a long time ago, there was a flying animal the size of some airplanes!

You know nothing.

Once evolution finds a trick that works, it tends to repeat it. Here are a few examples of prehistoric animals that look a lot like ones we know today.

In Cretaceous times (around 100 million years ago), North Africa was home to a huge river system and a bizarre menagerie of giant prehistoric predators -- including the Spinosaurus, a dinosaur even more fearsome than the Tyrannosaurus...

Feathers might have originated tens of millions of years before we'd thought, and a 3D rendering of ankylosaur nasal passages lends new insight into how they stayed cool.

If you get most of your information about ancient animals from vintage cartoons or action figures, then a lot of things that you think of as "dinosaurs" actually weren't. Learn about the definition of true dinosaurs and the evolutionary...

Hank fixes those of us who are probably wrong about what is and is not a dinosaur... and gives a refresher to those of us who do know this already.

The Great Dying hit life hard, but the species that survived took over the planet and diversified into many interesting forms, including the dinosaurs!

We can learn a lot from dinosaur fossils, but figuring how they behaved is a real challenge.

Meet Predator X, one of the most dangerous animals that ever lived!
