The artist’s impression shows a dromaeosaur, a type of feathered theropod, in the snow. This dinosaur group is popularly known as a raptor. A well-known dromaeosaur is Velociraptor, portrayed in the film Jurassic Park. Credit: Davide Bonadonna/Universidade de Vigo/UCL

First ‘warm-blooded’ dinosaurs may have emerged 180 million years ago

Researchers discover hidden step in dinosaur feather evolution

These ancient metamorphic rocks called gneisses, found on the Arctic Coast, represent the roots of the continents now exposed at the surface. The scientists said sedimentary rocks interlayered in these types of rocks would provide a heat engine for stabilizing the continents. Credit: Jesse Reimink. All Rights Reserved.

Coal core

Can coal mines be tapped for rare earth elements?

Magnified through a microscope, diatoms, which are a type of siliceous microalgae preserved within sediment, helped the researchers determine the salinity levels of the core samples. Photo courtesy of Jessica DePaolis.

The opening and closing of the Rocas Verdes Basin, a back-arc basin in Patagonia, as described by researchers at The University of Texas at Austin in a study published in Geology. Panels B and C illustrate the basin-closure process, in which an underlying portion of the oceanic crust is thrust into a magma chamber (B) and breaks off ahead of continental crust (C). The last two panels (C and D) show the oceanic plate and continental plate colliding together – squeezing the basin together into the Andes Mountains of Patagonia that we see today.

New step in tectonic squeeze that turns seafloor into mountains

The zircon crystals we found in river sand and rocks from Finland have signatures that point towards them being much older than anything ever found in Scandinavia, while matching the age of Greenlandic rock samples. Photo: Andreas Petersson.
