Newly found dinosaur is long-nosed cousin of Tyrannosaurus rex
Scientists have discovered a new species of long-snouted tyrannosaur, nicknamed Pinocchio rex, which stalked the Earth more than 66 million years ago.
Researchers find rare fossilized embryos more than 500 million years old
The Cambrian Period is a time when most phyla of marine invertebrates first appeared in the fossil record. Also dubbed the "Cambrian explosion," fossilized records from this time provide glimpses into evolutionary ...
Most of the sand in Alberta's oilsands came from eastern North America, study shows
They're called the Alberta oilsands but most of the sand actually came from the Appalachian region on the eastern side of the North American continent, a new University of Calgary-led study shows.
Late Cretaceous Period was likely ice-free
For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University ...
'Cascade of events' caused sudden explosion of animal life
The explosion of animal life on Earth around 520 million years ago was the result of a combination of interlinked factors rather than a single underlying cause, according to a new study.
Chinese super-rat roamed Earth 160 million years ago
A fossil of the oldest known ancestor of modern rats—an agile creature that could climb, burrow and eat just about anything—has been unearthed in China, scientists said Thursday.
Precious Western Australia mineral geologically 'young'
Scientists at Curtin University have chronicled the genesis of a particular type of iron deposit in the state's north, finding that the valuable mineral formed relatively late in Western Australia's evolution.
Biggest extinction in history caused by climate-changing meteor
(Phys.org) —It's well known that the dinosaurs were wiped out 66 million years ago when a meteor hit what is now southern Mexico but evidence is accumulating that the biggest extinction of all, 252.3m years ...
Dinosaurs, diets and ecological niches: Study shows recipe for success
A new study by a Canadian Museum of Nature scientist helps answer a long-standing question in palaeontology—how numerous species of large, plant-eating dinosaurs could co-exist successfully over geological ...
Oldest evidence of split between Old World monkeys and apes discovered
Two fossil discoveries from the East African Rift reveal new information about the evolution of primates, according to a study published online in Nature this week led by Ohio University scientists.
Striking gold: Earthquakes deposit precious metal
Solid gold can be deposited in Earth's crust "almost instantaneously" during earthquakes, said a study published in the journal Nature Geoscience on Sunday.
Deep ice cores show past Greenland warm period may be 'road map' for continued warming of planet
A new study by an international team of scientists analyzing ice cores from the Greenland ice sheet going back in time more than 100,000 years indicates the last interglacial period may be a good analog for ...
Ups and downs of biodiversity after mass extinction
The climate after the largest mass extinction so far 252 million years ago was cool, later very warm and then cool again. Thanks to the cooler temperatures, the diversity of marine fauna ballooned, as paleontologists ...
Scientists probe Canadian sulfide ore to confirm microbial activity in seawater 2.7 billion years ago
An analysis of sulfide ore deposits from one of the world's richest base-metal mines confirms that oxygen levels were extremely low on Earth 2.7 billion years ago, but also shows that microbes were actively ...
