New Plankton Species Evolved Within Thousands of Years After Chicxulub Impact Approximately 66 million years ago, the Chicxulub asteroid impact triggered massive global fires, climate shifts, and the extinction of dinosaurs and many other species. However, a new study from the University of Texas at Austin, published in Geology, reveals that life recovered much faster than previously estimated. Researchers, led by Chris Lowery, found that new species of microscopic plankton, such as the foraminifera Parvularugoglobigerina eugubina (P. eugubina), emerged within just a few thousand years—possibly under 2,000 years—after the disaster. This rapid evolution contrasts sharply with typical speciation timelines that span millions of years. The team refined the recovery timeline using helium-3 isotope concentrations in ocean sediments from six K/Pg boundary sites across Europe, North Africa, and the Gulf of Mexico. Helium-3 accumulates steadily, allowing precise sedimentation rate calculations despite post-impact disruptions like increased erosion from vegetation loss and the disappearance of calcareous plankton. These changes had previously skewed estimates, suggesting recovery took tens of thousands of years. The study indicates 10 to 20 new foraminifera species appeared within about 6,000 years, highlighting life's resilience. Co-author Timothy Bralower from Penn State noted this 'geologic heartbeat' recovery offers hope for modern ecosystems facing anthropogenic threats.

Where Is the Dinosaur‑Killing Asteroid? Evidence and Remnants

The 66 Myr impact hit at ~27,000 mph; the 12 km asteroid left a 180 km-wide Chicxulub crater, and a sesame-seed-sized fragment was found in a Hawaiian core. Read more: getnews.me/where-is-the-dinosaur-ki... #dinosaurextinction #chicxulub

Dinosaur Extinction Reshaped Rivers, Forests and Rock Layers

The K‑Pg impact 66 million years ago left an iridium‑rich clay layer in Wyoming’s Bighorn Basin, marking a shift from chaotic flood‑plain rocks to striped point‑bar deposits. Read more: getnews.me/dinosaur-extinction-resh... #dinosaurextinction #geology #kpg

Apparently, blaming an asteroid for wiping out all the dinosaurs is the flat Earth of extinction theories 😅

'Statistically, that shouldn’t have happened': Something very weird occurred in the ocean after the dinosaur-killing asteroid hit Not everything dies in a mass extinction. Sea life recovered in different and surprising ways after the asteroid strike 66 million years ago. Ancient fossils recorded it all.

Dinosaurs’ Decline Before Asteroid Impact May Be Misleading A study by University College London indicates that the perceived decline in dinosaur diversity before the asteroid impact may be due to gaps in the fossil record, not an actual decrease in species.

New study suggests dinosaurs were thriving until the asteroid impact—decline may be a fossil record illusion. #DinosaurExtinction #FossilRecord #Paleontology

Dinosaur extinction was not caused by global volcanic eruptions The Chicxulub meteorite impact, rather than volcanic activity, was the principal driver behind the extinction of the dinosaurs.
