The fossil record suggests extinction crises killing 10% of species occur roughly once per million years, while events killing around 65% occur roughly once per 100 million years — but these are episodic catastrophes, not a steady countdown toward the next mass extinction.
1+ week, 5+ day ago (1075+ words) David Raup's fossil-record kill curve estimated average waiting times for extinction events of different magnitudes. Those intervals describe an uneven historical distribution, not a periodic schedule or forecast of when the next crisis will occur. By Life Signs · Edited by…...
Prioritizing Quality Before Synthesis in Paleoenvironmental Hazard Science - Eos
2+ week, 1+ day ago (608+ words) Here, sediment deposits mark the high-water lines of floods that surged through the canyon centuries before any stream gauges were there to measure them. In particular, Baker and his colleagues studied slackwater deposits, fine-grained sediments emplaced by floodwaters in sheltered…...

Why the shells you find on the beach survived Earth’s worst extinction
3+ week, 21+ hour ago (577+ words) Scientists have found why some sea creatures survived Earth’s biggest extinction while others disappeared, showing that rising temperatures and falling oxygen levels played a major role, with warnings for today. A new study led by Stanford University describes how some…...
Paleontologists spent 20 years carbon-dating thousands of marine fossils, then used them to decode a process fundamental to Earth’s history
3+ week, 2+ day ago (691+ words) image: Scientists carbon-dated more than 7,500 marine fossils from ocean beds around the world and used that data to determine which environmental factors are most responsible for mixing together fossils from different time periods in the same stratum. view more Paleontologists…...
Mammal extinction followed the same rules for 130,000 years – until now
3+ week, 2+ day ago (797+ words) Traits that predicted mammal extinction for 130,000 years are changing, raising questions about how scientists identify species most at risk today. For 130,000 years, certain traits reliably predicted which mammals would go extinct and which would survive. A new study suggests that…...
How well do past extinctions predict extinction risk today?
