Scientists Identify the Halszkaraptor escuilliei, the Dinosaur that Resembled a Duck | |
This new, duck-like dinosaur is so wacky that scientists thought it was fake This Duck-Like Dinosaur Could Swim. That Isn't the Strangest Thing About It Smuggled fossil 'very weird' new species of amphibious dinosaur, say experts Synchrotron scanning reveals amphibious ecomorphology in a new clade of bird-like dinosaurs Dinosaur News: ScienceDaily Why 19th-Century Naturalists Didn't Believe the Platypus On Wednesday, a team of European scientists published a paper in Nature describing a one-of-a-kind dinosaur. The Halszkaraptor escuilliei had a long neck like a swan, clawed feet like a raptor, and hooked teeth like a crocodile. In addition, the creature appears to have had flippers, and the research team believes that H. escuilliei was capable of walking and swimming. The research team believes that the fossil of this unusual dinosaur dates from approximately 75 million years ago and originates from the Gobi Desert. Unfortunately, the fossil was poached from Mongolia and has since been sold to a number of private collectors, making it difficult for the scientists to identify its provenance with certainty. Due to the fossil's odd collection of characteristics, the team originally thought the fossil might have been a hoax. Paleontologist Andrea Cau of the University of Bologna and the Geological and Palaeontological Museum Giovanni Capellini in Italy told The Atlantic, "It was so strange that we suspected that it might have been a chimera--a mix of different skeletons glued together. It wouldn't be the first time." To determine that the fossil was comprised of a single creature, the team used synchrotron scanning, an X-ray technique. As the team reports in Nature, this examination revealed that the bones did, in fact, come from a single dinosaur. Nevertheless, some scientists are urging caution. Stephen Brusatte, a paleontologist at the University of Edinburgh, noted, "I just have some nagging doubts about whether the whole thing is one genuine skeleton."
