Latest Geochronology Stories
The first 500 million years after the Earth formed is a period known as the Hadean. Until recently, it was believed that this time in Earth's history was hellacious. A new study reveals that this assumption may be false and that the early Earth may have been surprisingly similar to present day.
Norwegian explorer Roald Amundsen might have been the first person to reach the South Pole, but an international team of scientists has discovered that he was actually beaten to his destination – by industrial air pollution.
Dating the formation of the Earth is a difficult process, because usually geological dating methods do not work as well.
In 1889 and 2012, there was large-scale melting of the Greenland ice sheet, and a new study reveals that rising temperatures and ash from Northern Hemisphere forest fires combined to cause the ice melting events.
New research on tree rings in Utah has revealed that some droughts of the past 576 years were much more severe than anything seen since the start of the 20th century.
A team of scientists has recently developed a new technique, described in the Proceedings of the National Academy of Sciences, to confirm the age of a 120,000-year-old sample of Antarctic Ice.
Glaciers are commonly thought to work like a belt sander. As they move over the land they scrape off everything—vegetation, soil, and even the top layer of bedrock. So scientists were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice.
The Life, Earth & Health Sciences Magazine EurekaMag.com has published 1,874 new articles on geologic mapping.
Scientists have announced the first-ever geological analysis of a rock sample performed on another celestial body – Mars.
An international team of glaciologists, led by Ohio State University, has discovered new and compelling evidence that the Italian Alps are warming at an unprecedented rate. The discovery was made less than 20 miles from the site where melting ice exposed the 5,000-year-old body of Ötzi the Iceman.

Credit: Rémih/Wikipedia (CC BY-SA 3.0) Tenontosaurus, meaning “sinew lizard”, is a genus of medium to large sized ornithopod dinosaur. The genus is known from the late Aptian to Albian ages of the middle Cretaceious period sediments of western North America, dating roughly between 115 to 108 million years ago. It was formerly thought to be a ‘hypsilophodont’, but since Hypsilophodontia is no...
Sharpirhynchia sharpi is a species of extinct brachiopod named after fossil collector Samuel Sharp (1814-1882). This species lived during the Lower Bathonian of the Middle Jurassic Period. It is found only in the United Kingdom, and numerous specimens have been taken from several sites, the first from Limekiln Quarry in Northampton, England. S. sharpi is roughly a half-inch long, with a slender beak and 21 to 31 ribs fanning out from the hinge. This lampshell brachiopod lived life as a...
Sauroposeidon, meaning “earthquake god lizard,” is a genus of sauropods dinosaur from the Aptian and Albian ages of the Early Cretaceous Period (110 million years ago). It was discovered in the southeast region of Atoka County, Oklahoma, not far from the border of Texas, in a claystone outcrop. The fossils were initially misidentified as pieces of petrified wood when they were found in 1994. A more detailed analysis in 1999 revealed they were truly dinosaurian bones. They were formally...
Qiaowanlong is a genus of sauropod dinosaur from the Albian stage of the Early Cretaceous Period (100 million years ago). It was discovered in the Yujinzi Basin of Gansu, China in 2007. It came from the geological formation called the Xinminpu Group. Qiaowanlong is known from articulated cervical (neck) vertebrae and a right pelvic girdle, as well as several unidentified bone fragments. It was the first brachiosaurid to have been found from China. Qiaowanlong is estimated to have been...
Qantassaurus is a genus of ornithopod dinosaur from the late Aptian to early Albian age of the Early Cretaceous Period (115 million years ago). It lived in Australia when the continent was still south of the Antarctic Circle, and was still part of the supercontinent Gondwana. Qantassaurus was discovered in 1996 during the third annual field season of the Dinosaur Dreaming Project, a dig jointly run by Monash University and Museum Victoria. It was found in the intertidal site known as Flat...
