Undersea Volcano Eruptions Caught On Video

Underwater volcanic eruptions and magma flows on the sea floor have been seen for the first time ever thanks to video captured by NOAA. James Williams talks to the lead scientist on the project to learn the story behind the explosive images.

Bird brain from the age of dinosaurs reveals roots of avian intelligence

Two perfectly articulated skeletons of the sheep-size dinosaur Psittacosaurus, found in China’s Yixian Formation. New research suggests they died in burrow collapses, not via volcanism, as previously thought. (Jun Liu, Institute of Paleontology and Paleoanthropology, Chinese Academy of Sciences)

Did the world’s best-preserved dinosaurs really die in ‘Pompeii-type’ events?

Herrerasaurus ischigualastensis is an early saurischian dinosaur. It shared a bipedal, running anatomy common to large carnivorous dinosaurs that would evolve in the future, but this dinosaur lived at a time when dinosaurs were small-bodied and rare.

Researchers studying ocean transform faults, describe a previously unknown part of the geological carbon cycle

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust, and the non-depletion of melt-mobile incompatible trace elements in the mantle.
