Strange phallus-shaped creature provides crucial missing link: Discovery pushes fossil record back 200 million years
Christopher Cameron of the University of Montreal's Department of Biological Sciences and his colleagues have unearthed a major scientific discovery - a strange phallus-shaped creature they found in Canada's ...
New to science: Find from 425 million years ago with body, limbs, eyes, gills and alimentary system preserved
An international team of researchers have made an extremely rare discovery of a species of animal - related to crabs, lobsters and shrimps – that is new to science.
Tropical collapse caused by lethal heat: Extreme temperatures blamed for 'dead zone'
Scientists have discovered why the 'broken world' following the worst extinction of all time lasted so long – it was simply too hot to survive.
In a brainless marine worm, researchers find the developmental 'scaffold' for the vertebrate brain
The origin of the exquisitely complex vertebrate brain is somewhat mysterious. "In terms of evolution, it basically pops up out of nowhere. You don't see anything anatomically like it in other animals," says ...
New study indicates carbon release to atmosphere ten times faster than in the past
The rate of release of carbon into the atmosphere today is nearly 10 times as fast as during the Paleocene-Eocene Thermal Maximum (PETM), 55.9 million years ago, the best analog we have for current global warming, according ...
Fossil of giant ancient sea predator discovered (w/ video)
Paleontologists have discovered that a group of remarkable ancient sea creatures existed for much longer and grew to much larger sizes than previously thought, thanks to extraordinarily well-preserved fossils ...
Palaeontologists solve mystery of 500 million-year-old squid-like carnivore
A study by researchers at the University of Toronto and the Royal Ontario Museum sheds new light on a previously unclassifiable 500 million-year-old squid-like carnivore known as Nectocaris pteryx.
Fossil find fills in picture of ancient marine life
Paleontologists have discovered a rich array of exceptionally preserved fossils of marine animals that lived between 480 million and 472 million years ago, during the early part of a period known as the Ordovician. ...
Fossils help identify marine life at high risk of extinction today
A detailed study of marine animals that died out over the past 23 million years can help identify which animals and ocean ecosystems may be most at risk of extinction today, according to an international ...
Animal functional diversity started out poor, became richer over time
Like a master painter who uses the same brush techniques to continually create original works of art, evolution has produced unique species to fill new or vacated ecological functions by tinkering with just ...
Sea creatures will get bigger and bigger (if we don't eat them first)
When life on Earth began around 3.6 billion years ago, all organisms were small. Indeed, it took some 2.5 billion years to evolve any organism that grows larger than a single cell.
New research shows our seas are in trouble
New research by the University of Sheffield has warned of the increasing risk of extinction to our marine life.
Ancient fossils confirmed among our strangest cousins
More than 100 years since they were first discovered, some of the world's most bizarre fossils have been identified as distant relatives of humans, thanks to the work of University of Adelaide researchers.
