We know that birds, such as this Archaeopteryx, evolved from dinosaurs but there have been persistent questions about how common the feathers were amongst their extinct relatives © The Trustees of the Natural History Museum, London

The first dinosaurs probably didn’t have feathers

Sediments may control location, magnitude of megaquakes

The team's experiments compared carbon's compatibility with the silicates that comprise the Earth's mantle (outer circle) to its compatibility with the iron that comprises the planet's core (inner circle) while under conditions mimicking the Earth's interior during its formative period. They found that more carbon would have stayed in the mantle than previously thought. Credit: Rebecca Fischer, Elizabeth Cottrell and Marion Le Voyer, Kanani Lee, and the late Erik Hauri.

Most of Earth’s carbon was hidden in the core during its...
