A discovery of more than a thousand dinosaur teeth, by a team of researchers from the University of Portsmouth, proves beyond reasonable doubt that Spinosaurus, the giant predator made famous by the movie Jurassic Park III as well as the BBC documentary Planet Dinosaur was an enormous river-monster.
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.
In the popular imagination, Vikings were fearsome blonde-haired warriors from Scandinavia who used longboats to carry out raids across Europe in a brief but bloody reign of terror. But the reality is more complex, says SFU Archaeology Prof. Mark Collard.
Researchers at the University of Oklahoma, the Smithsonian National Museum of Natural History, University of Oregon, and others report the unexpected discovery of an isolated short-faced bear toe bone from California's Channel Islands, presenting a puzzling scenario for how the largest mammalian carnivore to ever walk North America ended up in an island cave.
It's not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record. In a new paper, published today in Science Advances, an international team has identified a major extinction of life 233 million years ago that triggered the dinosaur takeover of the world. The crisis has been called the Carnian Pluvial Episode.
Domestic horses likely did not originate in Anatolia as previously suspected, according to a new study of ancient horse remains dating as far back as 9000 BCE. Instead, they may have been introduced to the peninsula -- which makes up most of modern-day Turkey -- and the nearby Caucasus region from the Eurasian Steppe by about 2000 BCE, during the Bronze Age.
An international collaboration between researchers at Queen Mary University of London and the Chinese Academy of Science in Nanjing has led to the discovery of world's oldest animal sperm inside a tiny crustacean trapped in amber around 100 million years ago in Myanmar.
Invaders, pirates, warriors - the history books taught us that Vikings were brutal predators who travelled by sea from Scandinavia to pillage and raid their way across Europe and beyond. Now cutting-edge DNA sequencing of more than 400 Viking skeletons from archaeological sites scattered across Europe and Greenland will rewrite the history books.
Through computed tomography (CT) imaging, West Virginia University geologist James Lamsdell led a team that found evidence of air breathing in a 340 million-year-old sea scorpion, or eurypterid.
The Ob, Yenisei, and Lena rivers flow into the Kara and Laptev seas and account for about half of the total freshwater runoff to the Arctic Ocean. The transport and transformation of freshwater discharge in these seas have a large impact on ice formation, biological productivity, and many other processes in the Arctic. Russian researchers have investigated the spreading of large river plumes -- that is, freshened water masses formed as a result of river runoff mixing with ambient saltwater -- in the Russian Arctic seas.
