How ocean ecosystems recovered after mass extinction event 66 million years ago
How ocean ecosystems recovered after mass extinction event 66 million years ago
An international team of scientists, led by the University of Bristol, have produced an unprecedented record of the biotic recovery of ocean ecosystems that followed after the last mass extinction, 66 million years ago. In an article published in the journal Nature , the team, which includes researchers from Southampton, University College London, Frankfurt and California, present a 13 million-year record of fossil plankton dynamics in the aftermath of near annihilation, providing a remarkable glimpse into how the marine ecosystem ‘reboots'.

UChicago Hong Kong campus wins international architectural design award
Researchers from the University of Chicago have used tools developed to explore 3-D movements and mechanics of modern-day fish jaws to analyze a fossil fish for the first time. Combined with CT imaging technology able to capture images of the fossil while it is still encased in rock, the results reveal that the 335-million-year-old shark had sophisticated jaws capable of the kind of suction feeding common to bony fishes like bass, perch, carp and also modern-day nurse sharks.

First human ancestors breastfed for longer than contemporary relatives
First human ancestors breastfed for longer than contemporary relatives
By analysing the fossilised teeth of some of our most ancient ancestors, a team of scientists led by the universities of Bristol (UK) and Lyon (France) have discovered that the first humans significantly breastfed their infants for longer periods than their contemporary relatives. The results, published in the journal Science Advances , provide a first insight into the practice of weaning that remain otherwise unseen in the fossil record.

Caught on video: Watch the ’living fossil’ fish of North America vacuum up its prey
The alligator gar, a toothy, narrow-snouted fish that resembles its namesake reptile, is the largest, native, freshwater predator in North America. They live primarily in Arkansas, Louisiana and Texas and can grow up to 10 feet long and 300 pounds. Long considered "trash fish" by fisherman who often throw them back because they aren't worth the trouble, gars have a special place in the hearts of biologists who study the evolution of fish.

Dinosaur brains from baby to adult
Dinosaur brains from baby to adult
New research by a University of Bristol palaeontology post-graduate student has revealed fresh insights into how the braincase of the dinosaur Psittacosaurus developed and how this tells us about its posture. Psittacosaurus was a very common dinosaur in the Early Cretaceous period - 125 million years ago - that lived in eastern Asia, especially north-east China.

Fossil shows how early mammals could swallow like their modern descendants
The 165-million-year-old fossil of a tiny, shrew-like animal shows the earliest example of modern hyoid bones-the ones that provide the ability to swallow food-in mammal evolution. The hyoid bones of Microdocodon gracilis -as well as all modern mammals, including humans-link the back of the mouth, or pharynx, to the openings of the esophagus and the larynx.

Small Wyoming dinosaur helps rewrite the evolutionary story of birds, flight
An artistic rendering of what Lori, scientifically known as Hesperornithoides miessleri, may have looked like when she was alive roughly 150 million years ago. Image by Gabriel Ugueto Scientists have long known that birds and dinosaurs are related, but as with many families, it's complicated. There are dinosaurs with feathers, but no wings, and dinosaurs with feathery wings that couldn't fly.

Blue colour tones in fossilised prehistoric feathers
Blue colour tones in fossilised prehistoric feathers
Examining fossilised pigments, scientists from the University of Bristol have uncovered new insights into blue colour tones in prehistoric birds. For some time, paleontologists have known that melanin pigment can preserve in fossils and have been able to reconstruct fossil colour patterns. Melanin pigment gives black, reddish brown and grey colours to birds and is involved in creating bright iridescent sheens in bird feathers.

Hue times two: a second look at the color of dinosaur eggs
Hue times two: a second look at the color of dinosaur eggs
After garnering worldwide attention last year for her research on the origins of egg color in birds, Yale paleontologist Jasmina Wiemann has taken a second look at her eggshells. Wiemann had found that all colors and spots on modern birds' eggs derived from a single evolutionary source among dinosaurs.

Feathers came first, then birds
Feathers came first, then birds
New research, led by the University of Bristol, suggests that feathers arose 100 million years before birds - changing how we look at dinosaurs, birds, and pterosaurs, the flying reptiles. It also changes our understanding of feathers themselves, their functions and their role in some of the largest events in evolution.

A high-heeled dinosaur?
A high-heeled dinosaur?
A 24-tonne dinosaur may have walked in a ‘high-heeled' fashion, according to University of Queensland research. UQ PhD candidate Andréas Jannel and colleagues from UQ's Dinosaur Lab analysed fossils of Australia's only named Jurassic sauropod, Rhoetosaurus brownei, to better understand how such an enormous creature could support its own body weight.

Challenges claim that 2-million-year-old fossil is human ancestor
Statistical analysis of fossil data shows that it is unlikely that Australopithecus sediba , a nearly two-million-year-old, apelike fossil from South Africa, is the direct ancestor of Homo , the genus to which modern-day humans belong. The research by paleontologists from the University of Chicago , published this week in Science Advances , concludes by suggesting that Australopithecus afarensis , of the famous "Lucy" skeleton, is still the most likely ancestor to the genus Homo .

Chewing versus sex in the duck-billed dinosaurs
Chewing versus sex in the duck-billed dinosaurs
The duck-billed hadrosaurs walked the Earth over 90-million years ago and were one of the most successful groups of dinosaurs. But why were these 2-3 tonne giants so successful? A new study, published in Paleobiology, shows that their special adaptations in teeth and jaws and in their head crests were crucial, and provides new insights into how these innovations evolved.

Flowering plants, new teeth and no dinosaurs: New study sheds light on the rise of mammals
A new study published April 30 in the Proceedings of the National Academy of Sciences identified three factors critical in the rise of mammal communities since they first emerged during the Age of Dinosaurs: the rise of flowering plants, also known as angiosperms; the evolution of tribosphenic molars in mammals; and the extinction of non-avian dinosaurs, which reduced competition between mammals and other vertebrates in terrestrial ecosystems.
