Giant Flying Reptiles Had Bird-Like Air Sacs

Long before birds took flight, giant reptiles called pterosaurs dominated the skies. Their wingspans varied widely, ranging from that of a sparrow to that of a Cessna. A study last month suggests the birds, some as tall as giraffes, got airborne by virtue of a leap-frog maneuver, relying on all...

How We Get Our Bearings

Research has suggested that animals and young children mainly rely on geometric cues (lengths, distances, angles) to help them get reoriented after a change of scene. Human adults, however, can also make use of feature cues (color, texture, landmarks) to get a sense of where they are. But which method...

The feathers were worn by Beipiaosaurus, which is a therizinosaur, small-headed theropods with long necks and giant claws. Most of the dinosaurs' bodies were covered with short and slender feathers that, based on the...
