'Amazing Dragon' Fossil Upends Origins of World's Largest Dinosaurs

LONG-NECKED DINOSAURS WERE the largest animals that ever walked on land. Moving cathedrals of sinew and bone, these plant-eating giants—called sauropods—could stretch up to 120 feet from head to tail. At their heaviest, they weighed a staggering 70 tons. But a new study published today in Nature Communications takes a whack at sauropods' conventional origin story. A new Chinese species of sauropod named Lingwulong shenqi—the “amazing dragon of Lingwu”—directly implies that major groups of Earth's largest land animals arose some 15 million years earlier than previously thought.

A new dinosaur discovered in China had feathers that may have glittered with the colors of the rainbow. Based on its stunningly preserved remains, scientists say the dinosaur’s head and chest seem to have been covered with iridescent feathers akin to those on modern hummingbirds.

(Andrew McAfee/Carnegie Museum of Natural History) Paleontologist Matthew Lamanna can still remember the day in 2014 when a colleague, Hesham Sallam, emailed him detailed pictures of fossils that had just been unearthed by his team in Egypt. From one photo, depicting the remains of a large lower jaw bone, Lamanna knew right away that Sallam had found a dinosaur.
