Earth's recovery from mass extinction could take millions of years
Earth’s recovery from mass extinction could take millions of years
How long will it take our biosphere to recover from the current climate crisis' It's a question that makes for a sobering examination of Earth's ongoing destruction. It's to the past, specifically the fossils of a tiny species that went out with the dinosaurs, that scientists have turned for the answer.

Untangling the evolution of feeding strategies in ancient crocodiles
Untangling the evolution of feeding strategies in ancient crocodiles
Ancient aquatic crocodiles fed on softer and smaller prey than their modern counterparts and the evolution of skull shape and function allowed them to spread into new habitats, reveal paleobiology researchers from the University of Bristol and UCL. For the study, published today in Paleontology , the team digitally reconstructed the skull of an extinct species of marine crocodile and compared it to similar living species to gain new insights into the diet of ancient crocodiles and their role in ecosystems around 230 million years ago.

Dinosaurs were thriving before asteroid strike that wiped them out
Dinosaurs were thriving before asteroid strike that wiped them out
Dinosaurs were unaffected by long-term climate changes and flourished before their sudden demise by asteroid strike, new research, co-authored by the University of Bristol, has found. Scientists largely agree that an asteroid impact, possibly coupled with intense volcanic activity, wiped out the dinosaurs at the end of the Cretaceous period 66 million years ago.

Dinosaurs were unaffected by long-term climate changes and flourished before their sudden demise by asteroid strike. Scientists largely agree that an asteroid impact, possibly coupled with intense volcanic activity, wiped out the dinosaurs at the end of the Cretaceous period 66 million years ago. Dinosaurs were likely not doomed to extinction until the end of the Cretaceous, when the asteroid hit.

Oldest evidence of mobility on Earth
Ancient fossils of the first ever organisms to exhibit movement have been discovered by an international team of scientists. Discovered in rocks in Gabon and dating back approximately 2.1 billion years, the fossils suggest the existence of a cluster of single cells that came together to form a slug-like multicellular organism that moved through the mud in search of a more favourable environment.

Newborn insects trapped in amber show first fossil evidence of how to crack an egg
Fossilised newborns, egg shells, and egg bursters preserved together in amber provide the first direct evidence of how insects hatched in deep time, according to a new article published today in the journal Palaeontology . One of the earliest and toughest trials that all organisms face is birth. The new findings give scientists evidence on how tiny insects broke the barrier separating them from life and took their first steps into an ancient forest.

New discovery pushes origin of feathers back by 70 million years
New discovery pushes origin of feathers back by 70 million years
An international team of palaeontologists, which includes the University of Bristol, has discovered that the flying reptiles, pterosaurs, actually had four kinds of feathers, and these are shared with dinosaurs - pushing back the origin of feathers by some 70 million years. Pterosaurs are the flying reptiles that lived side by side with dinosaurs, 230 to 66 million years ago.

Birds and dinosaurs evolved to dazzle with colourful displays
Birds and dinosaurs evolved to dazzle with colourful displays
Iridescence is responsible for some of the most striking visual displays in the animal kingdom. Now, thanks to a new study of feathers from almost 100 modern bird species, scientists have gained new insights into how this colour diversity evolved. Iridescence refers to the phenomena where colour changes when an object is viewed from different angles.

Tiny fossils reveal how shrinking was essential for successful evolution
Tiny fossils reveal how shrinking was essential for successful evolution
A new study published today in Nature, using research carried out at the University of Bristol, shows that getting smaller was a key factor contributing to the exceptional evolution of mammals over the last 200 million years. The origin of modern mammals can be traced back more than 200 million years to the age of dinosaurs.

Russian connections of reptile from the Jurassic Coast
Russian connections of reptile from the Jurassic Coast
The Triassic red rocks of the Devon coast around Sidmouth, some 240 million years old and pre-dating the earliest dinosaurs preserve fossil fishes, amphibians and reptiles, and a new specimen, uncovered with help from palaeontologists at the University of Bristol, shows distinct connections with Russia.

New species of rare ancient ’worm’ discovered in fossil hotspot
Scientists have discovered a new species of lobopodian, an ancient relative of modern-day velvet worms, in 430 million-years-old Silurian rocks in Herefordshire, UK. The team, comprising researchers from the universities of Oxford, Yale, Leicester and Manchester, and Imperial College London, has been able to three-dimensionally reconstruct the exceptionally well-preserved fossil using digital technology.

New dinosaur found in the wrong place, at the wrong time
A new dinosaur called Lingwulong shenqi or 'amazing dragon from Lingwu' has been discovered by an Anglo-Chinese team involving UCL. The announcement, published today , reports the surprising discovery of the new dinosaur which roamed the Ningxia Autonomous Region, northwest China, approximately 174 million years ago.

Creating 'synthetic' fossils in the lab sheds light on fossilisation processes
Creating ’synthetic’ fossils in the lab sheds light on fossilisation processes
A newly published experimental protocol, involving University of Bristol scientists, could change the way fossilisation is studied. In addition to directly studying fossils themselves, experimental treatments of fresh organismal remains can be utilised to study fossilisation. One commonly employed experimental approach is known as ‘artificial maturation', where high heat and pressure accelerate the chemical degradation reactions that normally occur over millions of years when a fossil is buried deep underground and exposed to geothermal heat and pressure from overlying sediment.

New sources of melanin pigment shake up ideas about fossil animals' colour
New sources of melanin pigment shake up ideas about fossil animals’ colour
A team of palaeontologists, led by University College Cork (UCC) and including the University of Bristol, have discovered new sources of the pigment melanin, calling for a rethink of how scientists reconstruct the colour of fossil birds, reptiles and dinosaurs. Many recent studies of fossil colour have assumed that fossilized granules of melanin - melanosomes - come from the skin.
