Alberta scientist unearths giant water lizard fossil in Hungary
Vancouver Sun
It grew up to six metres long and its toothy mouth and crocodile-like body was the terror of ancient rivers and shorelines many millions of years ago.

100-million-year-old liverwort mimicry in insects | Geology | Scoop.it
Camouflage and mimicry are pervasive throughout the biological world as part of the usual interactions between predators and their prey, allowing both to avoid detection. Among insects, the icons of mimicry include familiar stick and leaf insects, leaf-like moths and katydids.

Japan Just Found a Huge Rare-Earth Mineral Deposit That Can Supply The World For Centuries

Japan Just Found a Huge Rare-Earth Mineral Deposit That Can Supply The World For Centuries | Geology | Scoop.it
The newly discovered deposit is enough to "supply these metals on a semi-infinite basis to the world," the study's authors wrote in the paper. There's enough yttrium to meet the global demand for 780 years, dysprosium for 730 years, europium for 620 years, and terbium for 420 years.

Recent work challenges view of early Mars, picturing a warm desert with occasional rain | Geology | Scoop.it
The climate of early Mars is a subject of debate. A recent study suggests that the early Martian surface may not have been dominated by ice, but instead it may have been modestly warm and prone to rain, with only small patches of ice.

Cracking open the formation of fossil concretions

Cracking open the formation of fossil concretions | Geology | Scoop.it
Researchers developed a unified model of the formation mechanism of spherical carbonate concretions, which often contain exceptionally well-preserved fossils. The carbon in the carbonate originates from the organisms preserved inside the concretions, and the surrounding muddy matrix limits diffusion and permeability, and thus causes supersaturation of carbonate at a reaction front. Calcite precipitation occurs several orders of magnitude more rapidly than previously recognized in concretions. This understanding may have practical applications in sealing technology.

Fossil tracks in the Alps help explain dinosaur evolution  | Geology | Scoop.it
THAT the dinosaurs went out with a bang is well known. About 66m years ago a large space rock hit what is now southern Mexico. As a consequence, and with the assistance of some enormous volcanic eruptions on the other side of the planet, the terrible lizards were consigned to history. That left the world open for the rise of mammals.
