Scientists at TU Delft have successfully matched a layer of sediment from the dunes near Heemskerk to a severe storm flood that occurred in either 1775 or 1776.
An international team of scientists, led by Dr Stephen Barker of Cardiff University, has produced a prediction of what climate records from Greenland might look like over the last 800,000 years.
Nibbling by herbivores can have a greater impact on the width of tree rings than climate, new research has found.
The National Science Foundation (NSF) is accepting written requests from professional journalists to report on research--including studies of the ice sheet, climate change and atmospheric chemistry--supported in Greenland by NSF's Office of Polar Programs (OPP).
The end of the Norse colonies on Greenland have long been shrouded in mystery, and while archaeologists have been able to fill in some blanks, there is limited written evidence of the colonyâ€™s demise in the 14th and early 15th century.

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...
