Metabolism Decides Survival in Earth's Great Ocean Catastrophe

A Stanford-led study of the end-Permian mass extinction (the Great Dying) finds that survival hinged on metabolism: species with faster metabolisms could cope with warmer, oxygen-poor oceans, while slow-metabolizing brachiopods perished, leaving mollusks, fish, and echinoderms to dominate. The research links oxygen demand to warming and acidification, suggesting metabolism as a predictor of which modern ocean species may endure or vanish under current climate change.

Metabolism and Oxygen Rates Shaped Survival in Earth's Greatest Mass Extinction

A Stanford-led study shows that during the Permian–Triassic extinction about 252 million years ago, rapid warming and falling oxygen favored more metabolically active animals with efficient oxygen uptake (like mollusks) over slow, low-energy groups (such as brachiopods), helping explain why clams and snails survived while many ancient rivals vanished and highlighting how current ocean warming could drive similar patterns.

The Rise and Fall of a Saber-Toothed Predator During the Great Dying.

Fossil evidence shows that Inostrancevia, a saber-toothed apex predator, migrated 7,000 miles during the "Great Dying" mass extinction event 252 million years ago to find a new habitat before also going extinct. The fossils date from the late Permian period, an era of mass extinction so extreme that it is known as the "Great Dying." The event, triggered by climate change and fueled by volcanic eruptions, would have made it difficult for large predators such as Inostrancevia to find food. The researchers warn that Earth's largest mass extinction has parallels today as the planet undergoes another mass extinction.

Saber-Toothed Predator Unveils Insights into the "Great Dying" Extinction Event.

Fossils of Inostrancevia, a saber-toothed predator the size of a tiger, were discovered in South Africa's Karoo Basin, 7,000 miles from its original habitat in Russia. The creature filled a gap left by extinct top predators in a far-flung ecosystem before becoming extinct itself, indicating that apex predators could serve as early indicators of impending mass extinctions. Researchers draw parallels between these prehistoric patterns and current ecological crises, underscoring the importance of understanding ancient extinction events to predict and possibly mitigate today's biodiversity loss.
