Asteroid impact, not volcanoes, made the Earth uninhabitable for dinosaurs
Modelling of the Chicxulub asteroid impact 66 million years ago shows it created a world largely unsuitable for dinosaurs to live in. (2020-06-29)

First dinosaur eggs were soft like a turtle's
New research suggests that the first dinosaurs laid soft-shelled eggs -- a finding that contradicts established thought. The study, led by the American Museum of Natural History and Yale University, analyzed the eggs of two vastly different non-avian dinosaurs and found that they resembled those of turtles in their microstructure, composition, and mechanical properties. The research also suggests that hard-shelled eggs evolved at least three times independently in the dinosaur family tree. (2020-06-17)

First egg from Antarctica is big and might belong to an extinct sea lizard
An analysis led by researchers at The University of Texas at Austin has found that a mysterious fossil discovered in 2011 is a giant, soft-shell egg from about 66 million years ago. Measuring in at more than 11 by 7 inches, the egg is the largest soft-shell egg ever discovered and the second-largest egg of any known animal. (2020-06-17)

To think like a dinosaur
Palaeontologists from St Petersburg University have been the first to study in detail the structure of the brain and blood vessels in the skull of the ankylosaur Bissektipelta archibaldi. It was a herbivorous dinosaur somewhat similar in appearance to a modern armadillo. (2020-06-05)

Western Canadian scientists discover what an armoured dinosaur ate for its last meal
More than 110 million years ago, a lumbering 1,300-kilogram, armour-plated dinosaur ate its last meal, died, and was washed out to sea in what is now northern Alberta. This ancient beast then sank onto its thorny back, churning up mud in the seabed that entombed it--until its fossilized body was discovered in a mine near Fort McMurray in 2011. (2020-06-02)

Chinese pterodactyl wings its way to the United Kingdom
The first ever specimen of a pterodactyl, more commonly found in China and Brazil, has been found in the United Kingdom. (2020-05-28)

Finding a genus home for Alaska's dinosaurs
A re-analysis of dinosaur skulls from northern Alaska suggests they belong to a genus Edmontosaurus, and not to the genus recently proposed by scientists in 2015. (2020-05-27)

T. rex was a champion walker, super-efficient at lower speeds
While smaller dinosaurs needed speed, huge predators like T. rex were optimized for energy-efficient walking, according to a study published May 13, 2020 in the open-access journal PLOS ONE by Alexander Dececchi of Mount Marty College, South Dakota and colleagues. (2020-05-13)

T. rex's long legs were made for marathon walking
A new study by the University of Maryland's Thomas Holtz and his colleagues suggests that long legs evolved among the biggest dinosaurs to help them conserve energy as they ambled along searching for prey, rather than for speed as previously assumed. (2020-05-13)

Can we really tell male and female dinosaurs apart?
Scientists worldwide have long debated our ability to identify male and female dinosaurs. Now, research led by Queen Mary University of London has shown that despite previous claims of success, it's very difficult to spot differences between the sexes. (2020-05-12)

Jurassic Park got it wrong: UW Oshkosh research indicates raptors don't hunt in packs
A new University of Wisconsin Oshkosh analysis of raptor teeth published in the peer-reviewed journal Palaeogeography, Palaeoclimatology, Palaeoecology shows that raptorial dinosaurs likely did not hunt in big, coordinated packs like dogs. Though widely accepted, evidence for this behavior is relatively weak. Recently, scientists have proposed a different model for behavior in raptors that is thought to be more like Komodo dragons, in which individuals may attack the same animal but cooperation is limited.

Arctic Edmontosaurus lives again -- a new look at the 'caribou of the Cretaceous'
Published in PLOS ONE today, a study by an international team from the Perot Museum of Nature and Science in Dallas and Hokkaido University in Japan further explores the proliferation of the most commonly occurring duck-billed dinosaur of the ancient Arctic as the genus Edmontosaurus. The findings reinforce that the hadrosaurs -- dubbed 'caribou of the Cretaceous' -- had a geographical distribution of approximately 60 degrees of latitude, spanning the North American West from Alaska to Colorado. (2020-05-06)

New fossils rewrite the story of dinosaur -- and change the appearance of Spinosaurus
Scientists have long opposed the idea that dinosaurs lived in aquatic habitats. Now, an international team of researchers, supported by the National Geographic Society, has discovered unambiguous evidence that Spinosaurus aegyptiacus, the longest predatory dinosaur known to science, was aquatic. (2020-04-29)

Jurassic Park in Eastern Morocco: Paleontology of the Kem Kem Group
The Kem Kem beds in Morocco are famous for the spectacular fossils found there, including at least four large-bodied non-avian theropods, several large-bodied pterosaurs and crocodilians. In their study, published in the open-access journal Zookeys, an international group of scientists, led by Dr. Nizar Ibrahim and Prof. Paul Sereno, evaluate the geological and paleontological significance of the study area.

Studying pterosaurs and other fossil flyers to better engineer manmade flight
Pterosaurs were the largest animals ever to fly. They soared the skies for 160 million years -- much longer than any species of modern bird. Despite their aeronautic excellence, these ancient flyers have largely been overlooked in the pursuit of bioinspired flight technologies. In a review published in Trends in Ecology and Evolution researchers outline why and how the physiology of fossil flyers could provide ancient solutions to modern flight problems, like aerial stability and self-launch. (2020-04-15)

Synchrotron X-ray sheds light on some of the world's oldest dinosaur eggs
An international team of scientists led by the University of the Witwatersrand in South Africa, has been able to reconstruct, in the smallest details, the skulls of some of the world's oldest known dinosaur embryos in 3D, using powerful and non-destructive synchrotron techniques at the ESRF, the European Synchrotron in France. They found that the skulls develop in the same order as those of today's crocodiles, chickens, turtles and lizards. The findings are published today in Scientific Reports. (2020-04-09)

Palaeontology: New carnivorous dinosaur from New Mexico yields evolutionary insights
The discovery of a new species of dromaeosaurid -- a family of generally small to medium-sized feathered carnivores that lived during the Cretaceous Period -- is reported in Scientific Reports this week.

New species of Allosaurus discovered in Utah
A remarkable new species of meat-eating dinosaur, Allosaurus jimmadseni, was unveiled at the Natural History Museum of Utah. The huge carnivore inhabited the flood plains of western North America during the Late Jurassic Period, between 157-152 million years ago, making it the geologically oldest species of Allosaurus, predating the more well-known state fossil of Utah, Allosaurus fragilis. (2020-01-24)

Neutron source enables a look inside dino eggs
Did the chicks of dinosaurs from the group oviraptorid hatch from their eggs at the same time? This question can be answered by the length and arrangement of the embryo's bones, which provide information about the stage of development. But how do you look inside fossilized dinosaur eggs? Paleontologists from the University of Bonn used the neutron source of the Technical University of Munich at the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching. (2020-01-22)

New dinosaur discovered in China shows dinosaurs grew up differently from birds
A new species of feathered dinosaur has been discovered in China, and described by American and Chinese authors in The Anatomical Record. The one-of-a-kind specimen preserves feathers and bones that provide new information about how dinosaurs grew and how they differed from birds. (2020-01-15)

Researchers learn more about teen-age T.Rex
A team led by Holly Woodward Ballard, Ph.D., assistant professor of anatomy at Oklahoma State University Center for Health Sciences, studied two mid-sized tyrannosaur skeletons and concluded they were in fact teenage T.Rex and not a new pygmy species. They also studied the interior of the leg bones to determine age and how the dinosaurs grew and matured. (2020-01-01)

Dull teeth, long skulls, specialized bites evolved in unrelated plant-eating dinosaurs
Herbivorous dinosaurs evolved many times during the 180 million-year Mesozoic era, and while they didn't all evolve to chew, swallow, and digest their food in the same way, a few specific strategies appeared time and time again. An investigation of the skulls of 160 non-avian dinosaurs revealed the evolution of common traits in the skulls and teeth of plant-eating members of otherwise very different families of these extinct reptiles. The findings appear Dec. 5 in the journal Current Biology. (2019-12-05)

Adelphi, OHIO researchers determine dinosaur replaced teeth as fast as sharks
A meat-eating dinosaur species that lived in Madagascar some 70 million years ago replaced all its teeth every couple of months or so, as reported in a new study published in the open-access journal PLOS ONE. (2019-11-27)

New study shows a carnivorous dinosaur species regrew all its teeth every few months
A meat-eating dinosaur species that lived in Madagascar some 70 million years ago replaced all its teeth every couple of months or so, a new study has found, surprising even the researchers. In fact, Majungasaurus grew new teeth roughly two to 13 times faster than those of other carnivorous dinosaurs, says paper lead author Michael D. D'Emic, an assistant professor of biology at Adelphi University. Majungasaurus would form a new tooth in each socket every couple of months. (2019-11-27)
