Killer algae a key player in mass extinctions
Algae, not asteroids, were the key to the end of the dinosaurs, say two Clemson University researchers. Geologist James W. Castle and ecotoxicologist John H. Rodgers have published findings that toxin producing ...
Rolling the dice with evolution: Massive extinction will have unpredictable consequences
(PhysOrg.com) -- New research by Macquarie University palaeobiologist, Dr John Alroy, predicts major changes to the rules of evolution as we understand them now. Those changes will have serious consequences for future biodiversity ...
Last dinosaur before mass extinction discovered
A team of scientists has discovered the youngest dinosaur preserved in the fossil record before the catastrophic meteor impact 65 million years ago. The finding indicates that dinosaurs did not go extinct ...
Crashing comets not likely the cause of Earth's mass extinctions: new research
(PhysOrg.com) -- Scientists have debated how many mass extinction events in Earth's history were triggered by a space body crashing into the planet's surface. Most agree that an asteroid collision 65 million ...
Test shows dinosaurs survived mass extinction by 700,000 years
University of Alberta researchers determined that a fossilized dinosaur bone found in New Mexico confounds the long established paradigm that the age of dinosaurs ended between 65.5 and 66 million years ago.
A new day dawned fast: Recovery from marine mass extinction happened much faster than thought
(PhysOrg.com) -- In 1979, Luis Alvarez and his collaborators stunned the world with their discovery that an asteroid impact 65 million years ago probably killed off the dinosaurs and much of the the world's ...
History's normal rate of species disappearance is accelerating, scientists say
Biologist E.O. Wilson once pondered whether many of our fellow living things were doomed once evolution gave rise to an intelligent, technological creature that also happened to be a rapacious carnivore, fiercely territorial ...
International team maps 'big bang' of bird evolution
The genomes of modern birds tell a story of how they emerged and evolved after the mass extinction that wiped out dinosaurs and almost everything else 66 million years ago. That story is now coming to light, ...
Dinosaurs declined before mass extinction
Dinosaurs were dying out much earlier than the mass extinction event 65 million years ago, Natural History Museum scientists report in the Proceedings of the Royal Society journal today.
Giant snakes, fish among spectacular species found in Amazon
Spectacular species previously unknown to the outside world are being discovered in the Amazon rainforest at a rate of one every three days, environment group WWF said in a report published Tuesday.
The unknown crocodiles
Just a few years ago, crocodilians – crocodiles, alligators and their less-known relatives – were mostly thought of as slow, lazy, and outright stupid animals. You may have thought something like that ...
Prehistoric Fish Extinction Paved the Way for Modern Vertebrates
A mass extinction of fish 360 million years ago hit the reset button on Earth's life, setting the stage for modern vertebrate biodiversity, a new study reports.
Kimberley rocks tell first mass extinction of complex life
Volcanic eruptions across a vast area of what is now Western Australian and the Northern Territory 510 million years ago caused the first known mass extinction of complex life forms.
First plants caused ice ages: research
New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. Led by the Universities of Exeter and Oxford, the study is published today (February 1, 2012) in Nature Geoscience.
