Brains of newborns aren’t underdeveloped compared to other primates
Contrary to current understanding, the brains of human newborns aren't significantly less developed compared to other primate species, but appear so because so much brain development happens after birth, finds a new study led by UCL researchers.

How the fish got its shoulder
A new analysis of the bones and muscles in ancient fish gives new clues about how the shoulder evolved in animals - including us. The shoulder girdle - the configuration of bones and muscles that in humans support the movement of the arms - is a classic example of an evolutionary 'novelty'. This is where a new anatomical feature appears without any obvious precursors; where there is no smoking gun of which feature clearly led to another.

Prehistoric fish fills 100 million year gap in evolution of the skull
X-rays of an ancient jawless fish shows earliest-known example of internal cartilage skull, unlike that of any other known vertebrate. A 455-million-year-old fossil fish provides a new perspective on how vertebrates evolved to protect their brains, a study has found. In a paper published in Nature today (Wednesday 20 September), researchers from the University of Birmingham, Naturalis Biodiversity Centre in Leiden, Netherlands; and the Natural History Museum have pieced together the skull of Eriptychius americanus.

New Oxford study sheds light on the origin of animals
A study led by the University of Oxford has brought us one step closer to solving a mystery that has puzzled naturalists since Charles Darwin: when did animals first appear in the history of Earth? The results have been published today in the journal Trends in Ecology & Evolution . Animals* first occur in the fossil record around 574 million years ago.

Multiple species of semi-aquatic dinosaur may have roamed pre-historic Britain
Palaeontologists at the University of Southampton studying a British dinosaur tooth have concluded that several distinct groups of spinosaurs - dinosaurs with fearsome crocodile-like skulls - inhabited southern England over 100 million years ago. The team, from the University's EvoPalaeoLab, carried out a series of tests on the 140 million year old tooth, discovered in the early 20th century, in a thick, complicated rock structure named the Wealden Supergroup.

Fossil of mosasaur with bizarre ’screwdriver teeth’ found in Morocco
Scientists have discovered a new species of rare mosasaur in Morocco, adding to evidence of the vast diversity of these marine reptiles 66 million years ago. Scientists have discovered a new species of mosasaur, a sea-dwelling lizard from the age of the dinosaurs, with strange, ridged teeth unlike those of any known reptile.

’Veggie’ dinosaurs differed in how they ate their food
Scientists discover differences in the way early herbivore dinosaurs ate their food Although most early dinosaurs were vegetarian, there were a surprising number of differences in the way that these animals tackled eating a plant-based diet, a new study reveals. Scientists used CT scans of dinosaur skulls to track the evolution of early dinosaur herbivores - reconstructing jaw muscles and measuring the animals' bite force to understand how dinosaur feeding evolved.

Climate change played key role in dinosaur success story
Climate change, rather than competition, played a key role in the ascendancy of dinosaurs through the Late Triassic and Early Jurassic periods. According to new research, changes in global climate associated with the Triassic-Jurassic mass extinction - which wiped out many large terrestrial vertebrates such as the giant armadillo-like aetosaurs - actually benefitted the earliest dinosaurs.

Prehistoric reptile casts turn out to be copies of priceless fossil destroyed in WWII
Scientists find copies of lost fossil destroyed in WWII hiding in a US museum. The world's first complete skeleton of a prehistoric reptile brought to the attention of science was discovered a little over 200 years ago and named ' Proteosaurus '. Unfortunately, that fossil was destroyed in an air raid in May 1941, during WWII, with no copies thought to exist.

New Scottish fossil sheds light on the origins of lizards
A fossil discovery from Scotland has provided new information on the early evolution of lizards, during the time of the dinosaurs, reports a study involving UCL researchers. The tiny skeleton discovered on the Isle of Skye, called Bellairsia gracilis , is only 6 cm long and dates from the Middle Jurassic, 166 million years ago.

Ancient 'sharks' appeared much earlier than previously thought
The first appearance of shark-like 'jawed fish' may have happened some 15 million years earlier than previously thought, according to new evidence. A handful of fossil teeth from a completely new species, uncovered from rock samples found in China, suggest jawed fish emerged some time at the end of the Ordovician, or beginning of the Silurian period, around 440 million years ago.

Extinct prehistoric reptile that lived among dinosaurs discovered
An extinct species of lizard-like reptile that belongs to the same ancient lineage as New Zealand's living tuatara has been discovered by a team involving a UCL researcher. The researchers describe the new species Opisthiamimus gregori , which once inhabited Jurassic North America about 150 million years ago alongside dinosaurs like Stegosaurus and Allosaurus , in a paper published in the Journal of Systematic Palaeontology .

April the museum dinosaur still revealing new discoveries
Recent research regarding a dinosaur nicknamed April which previously called Manchester Museum home has revealed rare new findings. Scientists made the discovery of gastroliths (stomach stones) inside the Tenontosaurus which is unusually rare. This represents the second oldest occurrence of gastroliths in an ornithopod dinosaur and the first to be identified in a more derived ornithopod.

Dinosaurs evolved different eye socket shapes to allow stronger bites
Large dinosaur predators, such as Tyrannosaurus rex, evolved different shapes of eye sockets to better deal with high bite forces, new research has shown. While in many animals - and most dinosaurs - the eye socket is just a circular hole in the skull housing the eyeball, this is very different in large carnivores.

Oldest European salamander fossil, discovered in Scotland, informs amphibian origins
Fossils discovered in Scotland represent some of the world's oldest salamanders, according to a new study led by UCL researchers. The research team analysed 166-million-year-old fossils of a type of animal called Marmorerpeton , found in Middle Jurassic rocks on the Isle of Skye. They found that it has several key salamander traits, but is not part of the modern group of salamanders.

Discovery of ’ghost’ fossils reveals plankton resilience to past global warming events
An international team of scientists from UCL, the Swedish Museum of Natural History, the University of Florence and Natural History Museum have found a remarkable type of fossilization that has remained almost entirely overlooked until now. The fossils are microscopic imprints, or "ghosts", of single-celled plankton, called coccolithophores, that lived in the seas millions of years ago, and their discovery is changing our understanding of how plankton in the oceans are affected by climate change.
