That depth puts the quake in the lower mantle, where seismologists expected earthquakes to be impossible. That's because under extreme pressures, rocks are more likely to bend and deform than they are to break with a sudden release of energy. But minerals don't always behave precisely as expected, said Pamela Burnley, a professor of geomaterials at the University of Nevada, Las Vegas, who was not involved in the research. Even at pressures where they should transform into different, less quake-prone states, they may linger in old configurations.

Like the fictional Palmer, 20-year-old Hazel Drew was brutally killed under mysterious circumstances. She died on July 7, 1908, and her body was discovered floating in a pond on July 11. And the deeper that investigators probed into her background and habits, the more convoluted the mystery became.

Edward of Woodstock, commonly known as the Black Prince, was born in 1330 and was the heir to the English throne. He became famous for a series of military victories in France during the Hundred Years' War that culminated in the capture of the French King Jean II. The name "Black Prince" was first recorded in the 16th century, but it's unclear how he got that name.

The cramped room, which also doubled as a storage room, was most likely shared by three people, who may have been related. The "slave room," which is around 172 square feet (16 square meters), contains three beds, a chamber pot and several metallic and fabric objects, as well as eight large ceramic jars. The archaeologists recently unearthed the room at Civita Giuliana, a large villa on the northern outskirts of Pompeii, according to a statement released Nov. 6 by The Archaeological Park of Pompeii.

This pushes back previous estimates of when the cratons first rose from the water, as various studies suggested that large-scale craton emergence took place roughly 2.5 billion years ago.

Fights between these animals — known as gorgonopsians, the dominant carnivores of the late Permian period (299 million to 251 million years ago) — were likely the result of competition between individuals vying for benefits, such as social dominance, desirable mates or territory. And they were probably not meant to be fatal, the study finds. Researchers made the discovery after analyzing a healed bite mark on a gorgonopsian skull discovered near Cape Town, South Africa.
