Malformed fossil plankton reveal heavy metal pollution might have contributed to some of the largest extinction events
Metal poisoning caused the malformation observed in ancient organisms and may have contributed to their extinction and that of many other species.
A study provides multiple lines of new evidence that pigments and the microbodies that produce them can remain evident in a dinosaur fossil.
When they’re not being the stars of various animated movies, penguins are playing an important role in evolutionary studies. Penguins are unique among modern birds in that they ‘fly’ through the water.
More than 20 million years ago, a short struggle took place in what is now the Dominican Republic, resulting in one animal getting its leg bitten off by a predator just before it escaped. But in the confusion, it fell into a gooey resin deposit, to be fossilized and entombed forever in amber.
The diversity of animal life that inhabited the coastlines of South West England 200 million years ago has been revealed in a study by an undergraduate at the University of Bristol.
Scientists from the University of Kansas are departing this month to investigate how climate, plate tectonics and other factors influenced evolution by bringing species together in modern-day Turkey 42 million years ago during the Eocene epoch.
Competition played a more important role in the evolution of the dog family (wolves, foxes, and their relatives) than climate change, shows a new international study published in PNAS.
Widespread species are at just as high risk of being wiped out as rare ones after global mass extinction events, says new research by UK scientists.
Researchers have examined one of the smallest parts of the fossil record–theropod teeth–to shed light on the evolution of dinosaurs at the end of the Cretaceous.
The Tyrannosaurus rex and its fellow theropod dinosaurs that rampage across the screen in movies like Jurassic World were successful predators partly due to a unique, deeply serrated tooth structure that allowed them to easily tear through the flesh and bone of other dinosaurs, says new research from the University of Toronto Mississauga (UTM).
An “absolutely exquisite” fossil of a snake that had four legs has been discovered by a team of scientists and may help show how snakes made the transition from lizards to serpents.
Mammals were evolving up to ten times faster in the middle of the Jurassic than they were at the end of the period, coinciding with an explosion of new adaptations, new research shows.
A newly identified species of feathered dinosaur is the largest ever discovered to have a well-preserved set of bird-like wings, research suggests.
Head-butting and canine display during male-male combat first appeared some 270 million years ago.
Scientists have discovered a striking new species of horned dinosaur (ceratopsian) based on fossils collected from a bone bed in southern Alberta, Canada.
An international team led by researchers from the Evolutionary Studies Institute (ESI) at the University of the Witwatersrand, Johannesburg, has obtained an age from rocks of the Great Karoo that shed light on the timing of a mass extinction event that occurred around 260 million years ago.
For more than 30 million years after dinosaurs first appeared, they remained inexplicably rare near the equator, where only a few small-bodied meat-eating dinosaurs made a living.
A newly-identified species of spike-covered worm with legs, which lived 500 million years ago, was one of the first animals on Earth to develop armour for protection.
South African and Argentinian palaeontologists have discovered a new 200 million year old dinosaur from South Africa, and named it Sefapanosaurus, from the Sesotho word “sefapano”.
Twelve years ago, footprints of carnivorous dinosaurs were discovered and excavated in a quarry near Goslar.
A new study of an otherworldly creature from half a billion years ago – a worm-like animal with legs, spikes and a head difficult to distinguish from its tail – has definitively identified its head for the first time, and revealed a previously unknown ring of teeth and a pair of simple eyes.
The tooth plate of just some millimeters in size had been in a box for more than 40 years, without being recognized after the discovery and preparation of the fish it belonged to.
