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.

Mammal Forerunner Sheds Light on Brain Evolution
Mammal Forerunner Sheds Light on Brain Evolution
Researchers from The University of Texas at Austin found a fossil of an extinct mammal relative with a clutch of 38 babies that were near miniatures of their mother. Eva Hoffman / The University of Texas at Austin. Compared with the rest of the animal kingdom, mammals have the biggest brains and produce some of the smallest litters of offspring.
