Fossilised remains of a fish that grew as big as a great white shark and the largest of its type ever found have been discovered by accident. (2021-02-15)

How rocks rusted on Earth and turned red
How did rocks rust on Earth and turn red? A Rutgers-led study has shed new light on the important phenomenon and will help address questions about the Late Triassic climate more than 200 million years ago, when greenhouse gas levels were high enough to be a model for what our planet may be like in the future. (2021-02-08)

Study sheds new light on the behaviour of the giant carnivorous dinosaur Spinosaurus
New research from Queen Mary University of London and the University of Maryland, has reignited the debate around the behaviour of the giant dinosaur Spinosaurus. (2021-01-26)

New skull of tube-crested dinosaur reveals evolution of bizarre crest
The first new skull discovered in nearly a century from a rare species of the iconic, tube-crested dinosaur Parasaurolophus was announced today in the journal PeerJ. The exquisite preservation of the skull, especially the bizarre tube-shaped nasal passage, finally revealed the structure of the crest after decades of disagreement. (2021-01-25)

All-purpose dinosaur opening reconstructed for first time
For the first time ever, a team of scientists, led by the University of Bristol, have described in detail a dinosaur's cloacal or vent -- the all-purpose opening used for defecation, urination and breeding. (2021-01-19)

Research explains why crocodiles have changed so little since the age of the dinosaurs
New research by scientists at the University of Bristol explains how a 'stop-start' pattern of evolution, governed by environmental change, could explain why crocodiles have changed so little since the age of the dinosaurs. (2021-01-07)

When dinosaurs disappeared, forests thrived
To understand how specific ecosystems were affected by the meteorite impact that led to the mass extinction of dinosaurs, a team of McGill scientists has analyzed the microscopic remains of plants from this period. They found that local plant communities and ecosystems experienced a long-term shift towards fewer aquatic plants and an increase in terrestrial plants, including trees such as birches and elms. Changes in rainfall patterns during the extinction event were relatively minor and short-lived. (2020-12-16)

My, what sharp teeth
A new analysis shows dinosaurs and gorgonopsians developed the same specific cutting tooth. The study shows gorgonopsians, a lineage more related to humans than dinosaurs, actually did it first. (2020-12-15)

My what sharp teeth you have!
In the dinosaur world, theropods are well known for having blade-like teeth with serrated cutting edges used for biting and ripping their prey. And until recently, the complex arrangement of tissues that gave rise to these terrifying teeth was considered unique to these meat-eating dinosaurs. A new study in Biology Letters discovers this same complex arrangement in a group of mammalian predecessors that were also meat eaters. (2020-12-15)

Research reveals unexpected insights into early dinosaur's brain, eating habits and agility
A pioneering reconstruction of the brain belonging to one of the earliest dinosaurs to roam the Earth has shed new light on its possible diet and ability to move fast. (2020-12-13)

Archaeopteryx fossil provides insights into the origins of flight
Moulting is thought to be unorganised in the first feathered dinosaurs because they had yet to evolve flight, so determining how moulting evolved can lead to better understanding of flight origins. Recently an international research discovered that the earliest record of feather moulting from the famous early fossil bird Archaeopteryx found in southern Germany in rocks that used to be tropical lagoons ~150 million years ago. The findings were published in Communications Biology. (2020-12-09)

Paleontologists find pterosaur precursors that fill a gap in early evolutionary history

Ireland's only dinosaurs discovered in antrim
The only dinosaur bones ever found on the island of Ireland have been formally confirmed for the first time by a team of experts from the University of Portsmouth and Queen's University Belfast, led by Dr Mike Simms, a curator and palaeontologist at National Museums NI. (2020-11-24)

T. rex had huge growth spurts, but other dinos grew "slow and steady"
By cutting into dinosaur bones and analyzing the growth lines, a team of researchers discovered that T. rex and its closest relatives got big thanks to a huge growth spurt in adolescence, while its more distant cousins kept on growing a little bit every year throughout their lives. (2020-11-24)

Not just lizards - alligators can regrow their tails too
A team of researchers from Arizona State University and the Louisiana Department of Wildlife and Fisheries have uncovered that young alligators have the ability to regrow their tails up to three-quarters of a foot, or 18% of their total body length. (2020-11-23)

New analysis refutes claim that dinosaurs were in decline before asteroid hit
New research suggests that dinosaurs were not in decline before the asteroid hit. The study contradicts previous theories and concludes that had the impact not occurred dinosaurs might have continued to be the dominant group of land animals. (2020-11-17)

Baby dinosaurs were 'little adults'
Paleontologists at the University of Bonn (Germany) have described for the first time an almost complete skeleton of a juvenile Plateosaurus and discovered that it looked very similar to its parents even at a young age. That could have important implications for how the young animals lived and moved around. The young Plateosaurus, nicknamed ''Fabian'', was discovered in 2015 at the Frick fossil site in Switzerland. (2020-11-06)

The first duckbill dinosaur fossil from Africa hints at how dinosaurs once crossed oceans

Most detailed every study into how animals evolve to better suit their environments shows that pterosaurs become more efficient at flying over millions of years before going extinct with the dinosaurs. (2020-10-28)

Cracking the secrets of dinosaur eggshells
Since the famous discovery of dinosaur eggs in the Gobi Desert in the early 1920s, the fossilized remains have captured the imaginations of paleontologists and the public, alike. Although dinosaur eggs have now been found on every continent, it's not always clear to scientists which species laid them. Now, researchers reporting in ACS Omega have narrowed down the list for an unknown eggshell from Mexico by comparing its microstructure and composition with four known samples. (2020-10-28)

Study reveals bat-winged dinosaurs had short-lived gliding abilities
Research Assistant Professor Dr Michael PITTMAN (Vertebrate Palaeontology Laboratory, Division of Earth and Planetary Science & Department of Earth Sciences) at The University of Hong Kong (HKU), recently showed that powered flight potential evolved at least three times and that many ancestors of close bird relatives neared the thresholds of powered flight potential, suggesting broad experimentation with wing-assisted locomotion before flight evolved. (2020-10-23)

These two bird-sized dinosaurs evolved the ability to glide, but weren't great at it
Despite having bat-like wings, two small dinosaurs, Yi and Ambopteryx, struggled to fly, only managing to glide clumsily between the trees where they lived, researchers report October 22 in the journal iScience. Unable to compete with other tree-dwelling dinosaurs and early birds, they went extinct after just a few million years. The findings support that dinosaurs evolved flight in several different ways before modern birds evolved. (2020-10-22)

Bat-winged dinosaurs that could glide
Despite having bat-like wings, two small dinosaurs, Yi and Ambopteryx, struggled to fly, only managing to glide clumsily between the trees where they lived, according to a new study led by an international team of researchers, including McGill University Professor Hans Larsson. Unable to compete with other tree-dwelling dinosaurs and early birds, they went extinct after just a few million years. The findings, published in iScience, support that dinosaurs evolved flight in several different ways before modern birds evolved. (2020-10-22)

Toothless dino's lost digits point to spread of parrot-like species
A newly discovered species of toothless, two-fingered dinosaur has shed light on how a group of parrot-like animals thrived more than 68 million years ago. (2020-10-06)

Body size of the extinct Megalodon indeed off the charts in the shark world
A new study shows that the body size of the iconic gigantic or megatooth shark, about 15 meters (50 feet) in length, is indeed anomalously large compared to body sizes of its relatives. (2020-10-05)

Dinosaur feather study debunked
A new study published in ''Scientific Reports'' provides substantial evidence that the first fossil feather ever to be discovered does belong to the iconic bird-like dinosaur, Archaeopteryx. This debunks a recent theory that the fossil feather originated from a different species. (2020-09-30)

New study reveals how reptiles divided up the spoils in ancient seas
While dinosaurs ruled the land in the Mesozoic, the oceans were filled by predators such as crocodiles and giant lizards, but also entirely extinct groups such as ichthyosaurs and plesiosaurs. Now for the first time, researchers at the University of Bristol have modelled the changing ecologies of these great sea dragons. (2020-09-30)

"Immortal" in tree resin
The phenomenon of using DNA from old fossils preserved in amber already inspired Hollywood - in the film Jurassic Park, scientists reproduce the DNA of dinosaurs extracted from a fossil mosquito and thereby resurrect them. In reality, however, all previous studies in which researchers took DNA samples from insects enclosed in tree resin were useless under the scientific method. Researchers now detected DNA from ambrosia beetles that were trapped in recent tree resin. (2020-09-30)

Naked prehistoric monsters! Evidence that prehistoric flying reptiles probably had
Pterosaur expert Dr David Unwin from the University of Leicester's Centre for Palaeobiology Research, and Professor Dave Martill, of the University of Portsmouth have examined the evidence that these creatures had feathers and believe they were in fact bald (2020-09-28)

Bird beak revealed by HKU-codeveloped laser imaging informs early beak function and development
Confuciusornis was a crow-like fossil bird that lived in the Cretaceous ~120 million years ago. It was one of the first birds to evolve a beak (Fig. 1). Early beak evolution remains understudied. Using an imaging technique called Laser-Stimulated Fluorescence, researchers at the University of Hong Kong (HKU) address this by revealing just how different the beak and jaw of Confuciusornis were compared to birds we see today. (2020-09-21)

Computational study of famous fossil reveals evolution of locomotion in 'ruling reptiles'
Scientists from the University of Bristol and the Royal Veterinary College (RVC) used three-dimensional computer modelling to investigate the hindlimb of Euparkeria capensis-a small reptile that lived in the Triassic Period 245 million years ago-and inferred that it had a ''mosaic'' of functions in locomotion. (2020-09-21)
