Engineers have designed a robotic spy plane that is modeled on the pterodactyls that swooped through the sky between 228 million to 65 million years ago, while dinosaurs tromped over the land below. Perhaps unsurprisingly, researchers say that their prototype is the first aircraft inspired by a pterosaur (the broader scientific name for all winged lizards).
Paleontologist Sankar Chatterjee partnered with engineer Rick Lind to design their “Pterodrone;” the two men say the work was driven in part by their admiration for the vesatility of pterosaurs. With lightweight bones and an intricate system of collagen fibers that strengthened their wings, [pterosaurs] ranged from the size of a sparrow to the size of a Cessna plane. “These animals take the best parts of bats and birds. They had the maneuverability of a bat but could glide like an albatross. Nothing alive today compares to the performance and agility of these animals” Chatterjee said [AP].

In the primeval forests of Europe, scaly lizards leaped from the treetops and glided safely to the ground, according to a new study. Paleontologists investigated the
