- 1The Trouble With Trilobites26 Jun 2017 · 10mTrilobites are famous not just because they were so beautifully functional, or because they happened to preserve so well. They’re known the world over because they were everywhere!
- 2When Did the First Flower Bloom?3 Jul 2017 · 10mDuring 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.
- 3The Tully Monster & Other Problematic Creatures11 Jul 2017 · 10mThere are animals in the fossil record that challenge some of our most basic ideas about what animals are supposed to look like. If there ever was a monster on this planet that was worthy of the name, it might have been the Tully Monster.
- 4Stegosaurs: Tiny Brains & Thagomizers17 Jul 2017 · 10mIf 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.
- 5What Colors Were Dinosaurs?24 Jul 2017 · 10mWe know a lot about dinosaurs but there’s one question that has plagued paleontologists for decades: what color were they?
- 6The Story of Saberteeth31 Jul 2017 · 10mSmilodon was a fearsome Ice Age cat, the size of a modern-day tiger, that had a pair of fangs nearly 18 centimeters long. But it was only the last and largest of the great sabertooths: ridiculously long canines had already been a trend for millions of years by the time Smilodon was prowling around. And you know what? Those giant teeth just might make a comeback.
- 7That Time Oxygen Almost Killed Everything7 Aug 2017 · 10mWhat if we told you that there was a time when oxygen almost wiped out all life on Earth? 3 billion years ago, when the world was a place you’d never recognize, too much of a good thing almost ruined everything for everybody.
- 8The Biggest Thing That Ever Flew14 Aug 2017 · 10mToday, we’re familiar with two types of flying vertebrates -- birds and bats. But over 66 million years ago, there was a giraffe-sized reptile that soared through the sky.
- 9Dimetrodon: Our Most Unlikely Ancestor21 Aug 2017 · 10mWith its lizard-like appearance and that distinctive sail on it back, Dimetrodon is practically the mascot of the Palaeozoic Era, a time before flowers, birds, mammals, and even crocodiles. But if you take a close look at this sail-backed animal, you might see a little bit of yourself.
- 10The Extinction That Never Happened28 Aug 2017 · 10mNatural history is full of living things that were long thought to have gone extinct only to show up again, alive and well. Paleontologists have a word for these kinds of organisms: They call them Lazarus taxa.
- 11The Strange Case of the Buzzsaw Jaws11 Sept 2017 · 10mThere are many fossils that challenge our ability to form even the most basic idea of how a living thing looked, or lived, or functioned. One of the longest-running of these mysteries involved a 270-million-year-old sea creature called Helicoprion that once swam the seas around the supercontinent of Pangea.
- 12The Age of Giant Insects18 Sept 2017 · 10mInsects outnumber humans by a lot and we only like to think we're in charge because we're bigger than they are. But insects and other arthropods weren’t always so small. About 315 million years ago during the Carboniferous Period, they were not only abundant: they were enormous.
- 13History's Most Powerful Plants26 Sept 2017 · 10mFossil fuels are made from the remains of extinct organisms that have been exposed to millions of years of heat and pressure. But in the case of coal, these organisms consisted largely of some downright bizarre plants that once covered the Earth, from Colorado to China.
- 14How Did Dinosaurs Get So Huge?2 Oct 2017 · 10mPart of why we’re so fascinated with extinct dinosaurs it’s just hard for us to believe that animals that huge actually existed. And yet, they existed! From the Jurassic to the Cretaceous Periods, creatures as tall as a five-story building were shaking the Earth.
- 15When The Earth Was Purple9 Oct 2017 · 10mBesides the blue of the oceans, the dominant color of our planet, as we know it, is green. But imagine a time when the Earth looked a little … purple.
- 16'Living Fossils' Aren't Really a Thing16 Oct 2017 · 10mCrocodiles, horseshoe crabs and tuatara are animals that have persisted for millions of years, said to have gone unchanged since the days of the dinosaurs. But even the most ancient-looking organisms show us that evolution is always at work.
- 17When Whales Walked23 Oct 2017 · 10mWe know whales as graceful giants bound to the sea. But what if we told you there was actually a time when whales could walk.
- 18An Illustrated History of Dinosaurs30 Oct 2017 · 10mOur image of dinosaurs has been constantly changing since naturalists started studying them about 350 years ago. Taken together, these pictures can tell us a whole lot about just how much we have learned. Let's explore the history of dinosaur science as seen through the history of dinosaur art.
- 19A Brief History of Geologic Time6 Nov 2017 · 10mBy looking at the layers beneath our feet, geologists have been able to identify and describe crucial episodes in life’s history. These key events frame the chapters in the story of life on earth and the system we use to bind all these chapters together is the Geologic Time Scale.
- 20The Search for the Earliest Life20 Nov 2017 · 10mMore than 4 billion years ago, the crust of the Earth was still cooling and the oceans were only beginning to form. But in recent years, we’ve started to discover that, even in this hellish environment, life found a way.
- 21The Facts About Dinosaurs & Feathers27 Nov 2017 · 10mOver the past 20 years, dinosaurs of all types and sizes have been found with some sort of fluff or even full-on plumage. These fuzzy discoveries have raised a whole batch of new questions so we're here to tell you everything we know about dinosaurs and feathers.
- 22The Last Time the Globe Warmed4 Dec 2017 · 10mImagine an enormous, lush rainforest teeming with life...in the Arctic. Well there was a time -- and not too long ago -- when the world warmed more than any human has ever seen. (So far)
- 23What Happened to the World's Greatest Ape?11 Dec 2017 · 10mProbably twice the size of a modern gorilla, Gigantopithecus is the greatest great-ape that ever was. And for us fellow primates, there are some lessons to be learned in how it lived, and why it disappeared.
- 24When Giant Fungi Ruled18 Dec 2017 · 10m420 million years ago, a giant feasted on the dead, growing slowly into the largest living thing on land. It belonged to an unlikely group of pioneers that ultimately made life on land possible -- the fungi.
