The Triassic Reptile With "Two Faces"
Figuring out what this creature’s face actually looked like would take paleontologists years. But understanding this weird animal can help us shine a light on at least one way for ecosystems to bounce back from even the worst mass extinction.
The Rise and Fall of the Tallest Mammal to Walk the Earth
It arose from rhino ancestors that were a lot smaller, but Paraceratherium would take a different evolutionary path. Believe it or not, it actually became so big that it probably got close to what scientists think might be the actual upper limit for a lan...
The Island of the Last Surviving Mammoths
The Wrangel Island mammoths would end up being the final survivors of a once-widespread genus. In their final years, after having thrived in many parts of the world for millions of years, the very last mammoths that ever lived experienced what’s known as...
