New research published today in eLife by researchers from the Institut Català de Paleontologia Miquel Crusafont (ICP) and the University of Bristol (UB) moves back the moment of the radiation of squamates ―the group of reptiles that includes lizards, snakes and worm lizards― to the Jurassic, a long time before current estimates.
Una nueva investigación publicada hoy en eLife por personal investigador del Institut Català de Paleontologia Miquel Crusafont (ICP) y la Universidad de Bristol (UB) retrasa el momento de la radiación de los escamosos ―el grupo de reptiles que incluye lagartos, serpientes y lagartos gusanos― al Jurásico, mucho antes de las estimaciones hechas hasta el momento.
Flying reptiles could change the colour of their feathers, research finds.
In Triceratops Traits, students work alongside paleontologists to solve an evolutionary mystery by analyzing and interpreting data from the fossil record under the premise that natural laws have operated the same throughout the history of life on Earth to fit 7th grade learning standards in Utah and 6th-8th grades around the U.S.
Over the two decades paleontologist Kevin Padian taught a freshman seminar called The Age of Dinosaurs, one question asked frequently by undergraduates stuck with him: Why are the arms of Tyrannosaurus rex so ridiculously short?
A group of Finnish, Swedish, and Norwegian geologists provide critical new evidence for the timing of volcanic activity in the Karoo province, the largest of the Jurassic magma systems. The remnants of the province are widespread in southern Africa and Antarctica.
Spinosaurus is the largest predatory dinosaur known - over two metres longer than the longest Tyrannosaurus rex - but the way it hunted has been a subject of debate for decades. In a new paper, published today in Nature, a group of palaeontologists have taken a different approach to decipher the lifestyle of long-extinct creatures: examining the density of their bones.
Danish and Swedish researchers have dated the enormous Hiawatha impact crater, a 31 km-wide meteorite crater buried under a kilometer of Greenlandic ice.

Relatively small, but fearsome-looking stegosaur measured about 2.8 metres (9 feet) from nose to tail—but scientists can’t tell whether the remains are those of an adult or juvenile.
A new analysis of Tyrannosaurus skeletal remains reveals physical differences in the femur, other bones and dental structures across specimens that could suggest Tyrannosaurus rex specimens need to be re-categorised into three distinct groups or species, reports a study published in Evolutionary Biology.
The asteroid which killed nearly all of the dinosaurs struck Earth during springtime. This conclusion was drawn by an international team of researchers after having examined thin sections, high-resolution synchrotron X-ray scans, and carbon isotope records of the bones of fishes that died less than 60 minutes after the asteroid impacted.
Approximately 80 miles from the westernmost reach of China’s Great Wall, paleontologists found relics of an even more ancient world. Over the last two decades, teams of researchers unearthed more than 100 specimens of fossil birds that lived approximately 120 million years ago, during the time of the dinosaurs.
Researchers in Japan, Sweden, and the US have unearthed evidence that low volcanic temperatures led to the fourth mass extinction, enabling dinosaurs to flourish during the Jurassic period.
New research led by the University of Bristol has revealed how giant 50-tonne sauropod dinosaurs, like Diplodocus, evolved from much smaller ancestors, like the wolf-sized Thecodontosaurus.
German and Austrian scientists took a closer look at the braincase of a dinosaur from Austria. The group examined the fossil with a micro-CT and found surprising new details: it was sluggish and deaf. The respective study got recently published in the scientific journal scientific reports.
A 72 to 66-million-year-old embryo found inside a fossilised dinosaur egg sheds new light on the link between the behaviour of modern birds and dinosaurs, according to a new study.
A new bird-like dinosaur that used brute strength to overcome its prey has been found by paleontologists combing through fossils found on the Isle of Wight, on the south coast of Great Britain.
Giant, long-necked sauropods, thought to include the largest land animals ever to have existed, preferred to live in warmer, more tropical regions on Earth, suggesting they may have had a different physiology from other dinosaurs, according to a new study led by researchers at UCL and the University of Vigo.
A groundbreaking study led by researchers at FAU and an international team of scientists conclusively confirms the time year of the catastrophic Chicxulub asteroid, responsible for the extinction of dinosaurs and 75 percent of life on Earth 66 million years ago. Springtime, the season of new beginnings, ended the 165 million year reign of dinosaurs and changed the course of evolution on Earth.
