Strange landscapes, scorching heat and (sometimes) mad crocodiles await scientists seeking clues to evolution's genius. Paleontologist Paul Sereno talks about his surprising encounters with prehistory -- and a new way to help students...

Asking questions almost always leads to finding answers, but those answers will often pose even more questions. Here are five mysteries started and later solved by science.

The event that killed the dinosaurs 66 million years ago might be the most famous mass extinction ever, but it's not the only one in Earth’s history, nor is it the worst... not by a long shot.

Sometimes it seems like the past favored large animals, but it turns out that each one on this list has a different reason for its size. Chapters View all Carboniferous & Permian periods 360 251 million years ago 1:04 DRAGONFLY Credit:...

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.

In which John Green, Hank Green, and Emily Graslie teach you about evolution. So, in the last 3.8 billion years, life on Earth has evolved from single-celled prokaryotes to the dizzying array of life we have today. So how did all this...

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

Everybody loves dinosaurs, and we wouldn't know nearly as much as we do if it weren't for a person named Mary Anning.

If you take it as a given that extinct dinosaurs were all weird and wonderful, then you gotta at least consider that Stegosaurus was one of the weirdest and wonderfulest.

While we know that birds are the descendants of dinosaurs, we don't think much about the ones that lived alongside them, and they are a hot topic amongst paleontologists today.

How do you make an archaeologist really mad, really fast? Ask her if she’s found any dinosaurs. SciShow helps you Know Your Scientists by explaining the many differences between archaeology and paleontology, and how they’re each awesome...

Scientists were able to measure the emission lines of antimatter! And we may have some new clues about how dinosaurs lost their teeth on the way to becoming birds.

Squeaks built a pretend time machine, and he and Mister Brown use their imaginations to travel back in time to learn all about the very first living thing! Second Grade Next Generation Science Standards Disciplinary Core Ideas: LS4.D:...

Renowned paleontologist Jack Horner has spent his career trying to reconstruct a dinosaur. He's found fossils with extraordinarily well-preserved blood vessels and soft tissues, but never intact DNA. So, in a new approach, he's taking...

Would you like to spend all day thinking about dinosaurs? Well, some scientists do! Find out all about what it means to be a paleontologist!

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

Emily Graslie joins us to share the wonder of how shoulders, humble as they may be, have played a huge role in the evolution of mammals the world over. Thanks to the Museum of Comparative Zoology at Havard and The Field Museum for...

SciShow News explains the forces at work behind the earthquake in Nepal, introduces you to a new species of dinosaur, and reveals a discovery in Antarctica.

Dino's back to share more dinosaur facts with you, and this time he has some incredible news: birds are the descendants of dinosaurs! Join him to learn the whole story!

Due to a revolution in our understanding of the tree of life, birds are dinosaurs, while dimetrodons are not. ___________________________________________ FYI: We try to leave jargon out of our videos, but if you want to learn more about...

During the Cretaceous Period, dinosaurs were more diverse, more fierce, and more strange than ever. But something else was happening under the feet of the terrible lizards: for the first time in history, there were flowers.

Bees and flowers have an amazingly close relationship. Flowers need bees in order to reproduce, and bees need flowers to feed their colonies. Take away one, and the other would disappear too. It begs the question: When it comes to...

With the non-avian dinosaurs extinct, it was time for mammals to take over. Finally, in the tiniest sliver of the history of life, humans emerge.

In this hilarious, whirlwind tour of the last four billion years of evolution, paleontologist and TED Fellow Lauren Sallan introduces us to some of the wildly diverse animals that roamed the prehistoric planet (from sharks with wings to...
