No, it’s not the mythical Loch Ness monster, but 170 million years ago Dearcmhara shawcrossi prowled the warm coastal waters of Scotland in pursuit of fish and other reptiles. Scientists announced the discovery of the previously unknown prehistoric marine reptile in the Scottish Journal of Geology today. An artist’s depiction shows a dolphin-like creature measuring about 14 feet from snout to tail that lived during the Jurassic Period. It’s a moderate-sized ichthyosaur, the dominant marine reptiles that lived in the time of dinosaurs. They were around for 150 million years, until they disappeared about 95 million years ago. This discovery fills in some of the information of the Early-to-Middle Jurassic timeline that has proven hard to crack for paleontologists.
Using data from dissections and the study of fossils, award-winning paleo-artist John Gurche recreates through art how dinosaurs and early human ancestors might have appeared. His work has been featured in National Geographic, on postage stamps, in “Jurassic Park” and more. Continue reading
Newly-unveiled fossils indicate a dinosaur known as Spinosaurus aegyptiacus was built to live part of the time in water, according to a report published online for the journal Science. Continue reading
New research published Friday by the University of New Mexico postulates that dinosaurs were not cold-blooded creatures as previously believed, yet not warm-blooded like mammals either. Instead, the study claims that dinosaurs were mesothermic — an intermediate stage between the two. Continue reading
