The Mysterious "Accidental Mummies" of Medieval Siberia

Russian archaeologists are once again digging at Zeleniy Yar, a remote excavation site near the Arctic circle. This same site produced nearly a dozen extraordinary mummies a few years ago — including unintentionally preserved corpses wearing copper masks. The researchers are now hoping to learn more about this… » 4/14/14 9:40am 4/14/14 9:40am

Did Microbes Cause The Earth's Most Devastating Mass Extinction?

A little over 250 million years ago, our planet experienced a mass extinction the likes of which have never been seen before or since. About 90% of all species were suddenly wiped out. And new study suggests it wasn't caused by an asteroid or super-volcano — but rather methane-spewing microbes. » 3/31/14 12:00pm 3/31/14 12:00pm

Imagine Trying To Outrun This 600-Pound "Chicken From Hell"

Say hello to Anzu wyliei, a newly discovered Cretaceous era dinosaur that roamed the Dakotas 66 million years ago. Measuring nearly 12 feet long and weighing over 600 pounds, it's the largest oviraptorosaur ever discovered in North America. » 3/19/14 3:40pm 3/19/14 3:40pm

America's first settlers were trapped in Beringia for 10,000 years

The ancestors of Native Americans came to the New World by walking over a land bridge across the Bering Strait. But there's a rather glaring 10,000 year gap in the story — one that could be explained by a migratory pause that lasted for millennia. » 2/28/14 8:00am 2/28/14 8:00am

Ask a paleontologist about the mystery behind this whale graveyard!

Over 5 million years ago, a mass stranding of whales created what is now a whale graveyard in modern day Chile. Just why those whales died was a mystery — until now. Nick Pyenson, the paleontologist who led the team that cracked the case, is here to answer your questions! » 2/27/14 10:30am 2/27/14 10:30am

Are all Native Americans descended from the Clovis people?

For the very first time, scientists have produced genetic evidence that today's indigenous North and South Americans are all descended from a single population that trekked across the Bering land bridge from Asia. » 2/13/14 4:00pm 2/13/14 4:00pm

This dramatic fossil shows an ancient marine reptile giving birth

This 248 million-year-old fossil is incredible for two reasons. First, it shows the tragic moment an Ichthyosaur died giving birth. Second, it's the oldest evidence of a live reptilian birth — about 10 million years older than previous samples. » 2/13/14 3:23pm 2/13/14 3:23pm

Here's a chicken wearing a prosthetic tail to walk like a dinosaur

You already know about the evolutionary areas of overlap between dinosaurs and modern-day birds. Now one group of researchers is using those similarities for science, by attaching a prosthetic tail to a chicken to study how dinosaurs might have walked. » 2/06/14 11:09am 2/06/14 11:09am

Feathered dinosaur death site could be an "animal Pompeii"

A series of fossil discoveries in the 1990s changed our understanding of the lives of early birds and mammals, as well as the dinosaurs they shared an ecosystem with. All those discoveries had one thing in common: they came from a small region in northern China that preserved what is now called the Jehol Biota. » 2/05/14 7:20am 2/05/14 7:20am

Newly discovered titanosaur was one of the largest land animals ever

Introducing Yongjinglong datangi, a titanosaur that lumbered across the fields of China during the Early Cretaceous period some 100 million years ago. The specimen discovered, a juvenile not yet fully grown, measured nearly 60 feet in length, making it one of the largest species to ever walk the Earth. » 1/31/14 6:00pm 1/31/14 6:00pm
