Researchers working with specimens at the University of Alaska Museum of the North have described a new species of hadrosaur, a type of duck-billed dinosaur that once roamed the North Slope of Alaska in herds, living in darkness for months at a time and probably experiencing snow. Ugrunaaluk (oo-GREW-na-luck) kuukpikensis (KOOK-pik-en-sis) grew up to 30… Read more

Imagine a world populated by woolly mammoths, giant sloths and car-sized armadillos – 50,000 years ago more than 150 types of these mysterious large-bodied mammals roamed our planet. But by 10,000 years ago, two-thirds of them had disappeared. Since the end of the 19th century, scientists have puzzled over where these “megafauna” went. In 1796… Read more

A newly identified dinosaur species, named Wendiceratops pinhornensis, could help paleontologists understand the secrets of how horned dinosaurs evolved. The new dinosaur was about 20 feet long, weighed over a ton, and roamed the earth about 79 million years ago. That makes it one of the oldest known members of the Ceratopsidae family, large-bodied horned… Read more

A substantial fraction of the Neanderthal genome can still be found in the DNA of modern humans, new research suggests. A new approach applied to analyzing whole-genome sequencing data from 665 people from Europe and East Asia shows that more than 20 percent of the Neanderthal genome survives in the DNA of this contemporary group… Read more
