Published Birds set foot near South Pole in Early Cretaceous, Australian tracks show



The discovery of 27 avian footprints on the southern Australia coast -- dating back to the Early Cretaceous when Australia was still connected to Antarctica -- opens another window onto early avian evolution and possible migratory behavior.
Published Plants that survived dinosaur extinction pulled nitrogen from air



Ancient cycad lineages that survived the extinction of the dinosaurs may have done so by relying on symbiotic bacteria in their roots to fix atmospheric nitrogen. The finding came from an effort to understand ancient atmospheres, but became an insight into plant evolution instead.
Published Multiple evolutionary trajectories in aquatic crocodiles



In the geological past, several groups of crocodiles evolved towards a morphology adapted to marine life. However, the extent of these adaptations and their evolutionary trajectories remained unknown. An exhaustive study of their morphology has now shed light on the evolutionary mechanisms at work, thanks to three-dimensional reconstructions.
Published When we feel things that are not there



The discovery of the phantom touch illusion provides insights into human perception and opens up new perspectives for interaction with virtual reality technology.
Published Study sheds light on how Earth cycles fossil-carbon



Researches used rhenium as a proxy for fossil carbon in order to quantify the rate at which Earth naturally releases carbon dioxide into the atmosphere and found that high rates of carbon breakdown persist across the different geographical profiles of a river basin.
Published New study reveals surprising insights into feeding habits of carnivorous dinosaurs in North America



New research sheds light on the dining habits of ancient carnivorous dinosaurs from Jurassic rocks of the USA. A recent study explores the bite marks left on the ancient bones of the giant long-necked sauropod dinosaurs like Diplodocus and Brontosaurus by carnivorous theropod dinosaurs.
Published Evolution of taste: Early sharks were able to perceive bitter substances



New genetic data show that humans and sharks share bitter taste receptors, even though their evolutionary pathways separated nearly 500 million years ago.
Published Recreation of ancient seawater reveals which nutrients shaped the evolution of early life



Scientists know very little about conditions in the ocean when life first evolved, but new research has revealed how geological processes controlled which nutrients were available to fuel their development.
Published Palaeo-CSI: Mosasaurs were picky eaters



Mosasaurs, those large marine reptiles from the long-gone Cretaceous world, were quite picky in their choice of diet. Researchers came to this conclusion after studying the wear marks on mosasaur teeth.
Published Why a surprising discovery, warming seas and the demise of the 'Meg' may spell trouble for more and more sharks



Some unexpected shark strandings and subsequent surprises following autopsies have, ironically, taken marine biologists millions of years back in time as they look to the future with concern. Adding chapters to an evolutionary tale involving the infamous megalodon shark (the 'Meg'), they think their work suggests there are more warm-blooded sharks out there than previously believed, and -- based on the Meg's demise -- these species may be at great risk from warming seas.
Published Window to the past: New microfossils suggest earlier rise in complex life



Microfossils may capture a jump in the complexity of life that coincided with the rise of oxygen in Earth's atmosphere and oceans, according to an international team of scientists.
Published Machine learning gives users 'superhuman' ability to open and control tools in virtual reality



Researchers have developed a virtual reality application where a range of 3D modelling tools can be opened and controlled using just the movement of a user's hand.
Published 450-million-year-old organism finds new life in Softbotics



Researchers have used fossil evidence to engineer a soft robotic replica of pleurocystitids, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.
Published Fossils tell tale of last primate to inhabit North America before humans



Paleontologists have shed light on the long-standing saga of Ekgmowechashala, based on fossil teeth and jaws found in both Nebraska and China. Ekgmowechashala is the last primate found in the fossil record before humans.
Published Frogs were Florida's first-known vertebrates from the Caribbean



A new fossil study shows that frogs from the genus Eleutherodactylus are geologically the oldest Caribbean vertebrates to be found in Florida. They made the journey 20 million years ago, when much of Florida was still underwater.
Published 'Jurassic worlds' might be easier to spot than modern Earth



An analysis finds telescopes could better detect potential chemical signatures of life in an Earth-like exoplanet that more closely resembles the age the dinosaurs inhabited than the one we know today.
Published Study links changes in global water cycle to higher temperatures



A new study takes an important step toward reconstructing a global history of water over the past 2,000 years. Using geologic and biologic evidence preserved in natural archives -- including 759 different paleoclimate records from globally distributed corals, trees, ice, cave formations and sediments -- the researchers showed that the global water cycle has changed during periods of higher and lower temperatures in the recent past.
Published Giant dinosaur carcasses might have been important food sources for Jurassic predators



Carnivorous dinosaurs might have evolved to take advantage of giant carcasses, according to a new study.
Published 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.
Published New species of mosasaur named for Norse sea serpent



Scientists have discovered a new species of mosasaur, large, carnivorous aquatic lizards that lived during the late Cretaceous. With 'transitional' traits that place it between two well-known mosasaurs, the new species is named after a sea serpent in Norse mythology, Jormungandr, and the small North Dakota city Walhalla near to where the fossil was found.
