Paleontological mystery: New study reveals ammonites thrived until their sudden extinction

SciTechDaily

A new study challenges the view that ammonites declined before their extinction 66 million years ago, showing instead that they remained globally diverse and robust. The research highlights that their extinction was influenced by a range of geographic and environmental factors, rather than an inevitable outcome. Ammonites bask in the Late Cretaceous sun.

Solving an age-old mystery: paleontologists shed new light on the extinction of the woolly rhinoceros

SciTechDaily

Woolly rhinos were once widely distributed across northern and central Eurasia before becoming extinct about 10,000 years ago. Credit: Mauricio Anton Advanced computer modeling shows that persistent human hunting contributed to the extinction of the woolly rhino by blocking their migration to new habitats during post-ice age warming. This underlines the continued impact of human … Read more

The Megafauna Mystery: Scientists Uncover New Clues to What Happened to North America’s Largest Animals

Fifty thousand years ago, North America was home to megafauna such as mammoths and sabre-tooth tigers. Their extinction, possibly due to the arrival of humans or climate change, remains unsolved. Using ZooMS technology, researchers analyzed ancient bones from the Smithsonian Museum, highlighting the importance of preserving archaeological collections for future discoveries. USNM 23792, Mammuthus primigenius … Read more

Scientists discover Antarctica’s lost river 34 million years later

Scientists have discovered that a river comparable in size to the Rio Grande once dominated West Antarctica, offering a rare glimpse of the continent’s land covered in ice today. It is believed that the 900-mile-long waterway flowed about 44 to 34 million years ago, shortly before the continent’s immensely thick ice sheets began to build … Read more

The 180-million-year-old secret of evolution: Scientists discover potential origin of the first ‘warm-blooded’ dinosaurs

SciTechDaily

Recent research indicates that some dinosaurs may have evolved the ability to regulate their body temperature internally during the Early Jurassic period, allowing them to adapt to colder climates and survive environmental challenges. The artist’s impression shows a dromaeosaur, a type of feathered theropod, in the snow. This group of dinosaurs is popularly known as … Read more
