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.

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.

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.

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.

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.

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.

Diversity on land is not higher today than in the past
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.

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.
