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.

The rich levels of biodiversity on land seen across the globe today are not a recent phenomenon: diversity on land has been similar for at least the last 60 million years, since soon after the extinction of the dinosaurs. According to a new study led by researchers at the University of Birmingham and involving an international team of collaborators, the number of species within ecological communities on land has increased only sporadically through geological time, with rapid increases in diversity being followed by plateaus lasting tens of millions of years.

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.

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.

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.

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.

A new study published today in Nature 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. But while dinosaurs evolved to become some of the largest land animals, for the following 150 million years, the ancestors of all modern mammals pursued an entirely different strategy: getting very small.

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.

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.

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.

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.

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.

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.

A rare fossil from an early bird gives a unique insight into how modern birds evolved from dinosaurs Last updated on Wednesday 16 May 2018 An international team of researchers has pieced together the three-dimensional skull of an iconic, toothed bird that represents a pivotal moment in the transition from dinosaurs to modern-day birds.

Mass extinctions were followed by periods of low diversity in which certain new species dominated wide regions of the supercontinent Pangaea, reports a new study. The findings indicate that mass extinctions may have predictable consequences and provide insights into how biological communities may be expected to change in the future as a result of current high extinction rates.
