Latest Permian–Triassic extinction event Stories
The theory that all animal life emerged from the sea has been well covered, but much less is known about the creatures that went back. Whales, dolphins, seals and sea turtles are examples of marine tetrapods--an exceptional group of animals that moved from the sea to the land and back again.
Chuck Bednar for redOrbit.com - @BednarChuck New evidence of severe losses in brachiopods in the northern Boreal latitudes around the island of Spitsbergen suggest that the controversial Capitanian extinction event that occurred about 262 million years ago should be classified as a true “mass extinction” event. Previously, the Capitanian extinction event was known only from equatorial settings, and thus its status as a full-fledged global crisis was controversial. However, the...
Environment was just right--a 'Goldilocks effect'-- for well-preserved swim tracks from the Early Triassic age.
Paleontologists from the University of Zurich now reveal that climate catastrophes in the past played a crucial role in the dominance of ray-finned fish today.
Scientists have debated how nothosaurs swam for a long time. One theory is the reptiles used their paddle-like feet to row with a back-and-forth motion. A second theory has the dinosaurs sweeping their forepaddles in a figure-eight motion
Over 250 million years ago a mysterious event dubbed the Great Dying wiped out 90 percent of all species on Earth. Scientists have debated the culprit behind this mass extinction event for years, and a new study from MIT researchers has concluded that countless, tiny microbes...
A research team from MIT has determined that the end-Permian extinction took place over 60,000 years — give or take 48,000 years. From a geologic perspective, that's nearly instantaneous.
At the end of the Permian period, approximately 250 million years ago, a mass extinction occurred that was so severe it remains the most traumatic known species die-off in Earth's history.
A new study examines how a group of ancient mammalian relatives coped with a mass extinction event in the prehistoric past as a way to glimpse into the potential future.
Sorry, Felix and Oscar, but an international team of researchers have found a real-life odd couple that puts Neil Simon’s famous duo to shame – a mammal forerunner and an ancient amphibian, which were discovered sharing a burrow during the Early Triassic period.
