Dinosaurs and the reduced felt effect of gravity

Herre's yet another piece of the picture which I seem to have overlooked here. The heaviest birds which can take off or land in our present world are around 30 lbs, including albatrosses and buzzards, and the largest flying eagles are around 25 lbs, i.e. the largest berkuts. They get one or two berkuts that size every fifty years or so; any larger than that, and they can't take off or land, and they perish. The Argentinian teratorn, of course, was a 200 lb eagle with a 25' wingspan, yet another thing which can't happen in present gravity

Quetzalcoatlus! The largest flying creature of all timeBy 1975, studies of the specimen by Lawson and his supervisor, Wann Langston, Jr. Had determined that the animal, a 65 million year old pterodactyl from the Age of Dinosaurs, had a wing spread of about 40 feet, greater than a 4-place Cessna airplane or an F-18 fighter. It was about twice as large as the biggest pterodactyl known up to that time. With the discovery of additional, though smaller, fossilized skeletal remains in the Big Bend in 1973, it was possible to reconstruct the entire skeleton of the pterodactyl which Lawson named Quetzalcoatlus northopi. Based upon what had been learned from these discoveries, the world-renowned aeronautical engineer, Paul MacCready, with the assistance of Professor Langston created a large flying replica of Quetzalcoatlus which performed over the California desert for the Smithsonian Museum's IMAX film "on the Wing" in 1985. Lawson's discovery attracted world-wide attention, being reported in newspapers and magazines and on TV from New York to Tokyo and Canada to Argentina. "On the Wing" was shown around the world. ABC 20-20, the news program, produced a 20 minute segment on MacCready's work, and Sir David Attenborough traveled to Texas to film segments for his BBC series "Lost Worlds - Vanished Lives." Quetzalcoatlus continues to attract attention within scientific circles and the press because of the exciting questions it raises about how the long extinct pterodactyls flew, how big a flying creature can be, and why such successful animals went extinct along with the dinosaurs sixty-five million years ago.

Either that, or do it in a world where gravity is less of a problem. That's the conclusion most of the people studying the problem are coming to at present.
