The Huge Extinctions We Are Just Now Discovering
What graptolites tell us is a story of incredible changes in the ocean, of periods where the oceans became poisonous and suffocating before eventually clearing up again. They unlock extinctions and recoveries that scientists didn't see....

What’s Eating The Titanic?
When a ship sinks, lots of factors, like the ship’s materials, the water quality, and the depth of the seafloor all play a role in determining how long the ship will last down there - as a result, the Titanic will be gone in fifty years,...

Something's Been Making Weird Pits in the Seafloor
For years, scientists couldn't solve the mystery of strange pits on the floor of the North Sea. Initially they blamed methane seeps, but it seems like the pits were actually made on porpoise.

The Extinction That Never Happened
Natural 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.

How Worm Holes Ended Wormworld
Elongated tubes, flat ribbons, and other “worm-like” body plans were so varied and abundant that a part of the Ediacaran is sometimes known as Wormworld. But in the end, the ancient Wormworld was ended by the actions of its very own worms.
