Paleontologists find evidence of new mass extinction 233 million years ago

Sept. 16 (UPI) — Paleontologists have unearthed evidence of a new mass extinction that occurred during the Late Triassic, some 233 million years ago.

The extinction event, which scientists dubbed Carnian Pluvial Episode, was characterized by significant reductions in biodiversity and the loss of 33 percent of marine genera.

In a new paper, published Wednesday in the journal Science Advances, researchers suggest the episode may have created the ecological space for the emergence of a variety of important modern plant and animal lineages — including conifers, insects, dinosaurs, crocodiles, lizards, turtles and mammals.

Through analysis of both paleontological assemblages and geological evidence, researchers confirmed that biodiversity declines coincided with stark chemical changes in the ocean and atmosphere.

Scientists suspect these changes were triggered by massive volcanic eruptions in what’s now Alaska and British Columbia.

“The eruptions peaked in the Carnian,” lead study author Jacopo Dal Corso said in a news

Study shows difficulty in finding evidence of life on Mars

In a little more than a decade, samples of rover-scooped Martian soil will rocket to Earth.

While scientists are eager to study the red planet’s soils for signs of life, researchers must ponder a considerable new challenge: Acidic fluids—which once flowed on the Martian surface—may have destroyed biological evidence hidden within Mars’ iron-rich clays, according to researchers at Cornell University and at Spain’s Centro de Astrobiología.

The researchers conducted simulations involving clay and amino acids to draw conclusions regarding the likely degradation of biological material on Mars. Their paper, “Constraining the Preservation of Organic Compounds in Mars Analog Nontronites After Exposure

Evidence pointing to Australia Apple Card launch soon, other countries in 2020

Evidence is pointing to an imminent Apple Card launch in Australia, plus launches in other countries by the end of 2020 as Apple seeks out partnering banks.

The Apple Card launched in the U.S. in 2019 via issuing bank Goldman Sachs. The credit card was built with digital use in mind and lives within the Apple Wallet app, though customers can opt for a physical card made of titanium.

In an investigation conducted by MacRumors, evidence of a global expansion of the Apple Card has been uncovered. An international launch of a credit card would be nearly impossible to hide due to regulatory processes alone, so some details inevitably leak out.

An Australian banking employee offered some information about Apple’s plans— stating that the the company had reached out to banks in multiple regions to prepare for a launch by the end of 2020. The banker speculates that the

Evidence suggests an animal that roamed with the dinosaurs went into a hibernation-like state to survive

New evidence suggests the Lystrosaurus species that roamed the Earth with the dinosaurs went into a state of hibernation to survive what is modern day Antarctica.

The Lystrosaurus is a mammal-like animal from the early Triassic period that roamed modern day regions such as India, South Africa and Antarctica over 250 million years ago. It has tusks like an elephant and a beak similar to a turtle, and it was roughly the size of a pig.

Scientists at the University of Washington used fossils of the animal’s tusks to test for stress differences between the species living in polar climates and warmer ones, such as in Africa. The tusks are key because they can measure periods of time in the animal’s life, similar to rings on a tree.

They found prolonged stress consistent with animals
