In a new report, paleontologists Lauren Sallan and Jack Stack re-examine the “enigmatic and strange” prehistoric fish Tanyrhinichthys mcallisteri.

300-million-year-old fish resembles a sturgeon but took a different evolutionary path

Pictured left is an exceptionally preserved male pollen cone of Araucaria huncoensis showing characteristic cylindrical shape and many long, pointed bracts at the base. Pictured right is a leafy branch fossil of Araucaria huncoensis, showing rare preservation of a branching point connecting two leafy branch segments and a connected growth point on the right segment. The branches are usually shed from the tree as individual segments.

Scientists examined hundreds of samples taken along the global ridges that contain recycled ancient oceanic crust in variable amounts. "Depleted" segments of the ridge received lower than "normal" amounts of recycled crust, while "enriched" segments contain a larger proportion of recycled crust.

Seismic recordings with bell ringing signals in four European locations to mark the passage of time: Lunas (France), Riolos (Greece), Sta. Marيa de Montmagastrell (Spain) y Oriolo (Italy). Each plot corresponds to one day. Each trace represents the same minute at every hour on that day. Time scale is in seconds. (Image: Jordi Dيaz, ICTJA-CSIC)

Coal-burning in Siberia led to climate change 250 million years ago

Earthquakes send sound waves through the Earth. Seismograms record the echoes as those waves travel along the core-mantle boundary, diffracting and bending around dense rock structures. New research from University of Maryland provides the first broad view of these structures, revealing them to be much more widespread than previously known. Credit: Doyeon Kim/University of Maryland

Scientists detect unexpected widespread structures near Earth’s core

The Andes seen from space. The height of the Andes, like the height of other mountain ranges on Earth, is determined by tectonic forces (Credit: NASA; Astronaut photograph ISS059-E-517).

Which factors control the height of mountains?

New Curtin University research on the remixing of Earth's stratified deep interior suggests that global plate tectonic processes, which played a pivotal role in the existence of life on Earth, started to operate at least 3.2 billion years ago. Credit: Professor Zheng-Xiang Li

Remixed mantle suggests early start of plate tectonics
