...locomotion from the fossil evidence. At last week's meeting, for example, scientists debated whether pterosaurs walked on two legs, like birds, or crawled on all fours, like bats. Hundreds of footprints discovered at dozens of sites in the U.S. and Europe over the past few years, argues Martin Lockley of the University of Colorado at Denver, strongly support the latter conclusion. The pattern of these footprints, which range in size from 1 in. to 5 in., suggests that pterosaurs held their bodies in a semierect position, with their long wings folded back so that their clawlike fingers gripped...
...also swirls around the question of how pterosaurs managed to become airborne. Some scientists think the beasts launched themselves from a running start, while others believe they were so clumsy on the ground that they would have had to drop from cliffs or trees to attain a flightlike glide. Lockley, for one, argues that pterosaurs had to be capable of birdlike takeoffs and landings if only because so many pterosaur footprints come from mudflats along the seashore. If they were incapable of flying off after landing in such areas, he says, they would have quickly died...
...bugs' aversion to frost has kept them out of the Midwest and Northeast, but even that may change. Tim Lockley, an entomologist at the Agriculture Department's fire-ant lab in Gulfport, Mississippi, says the ants have now settled in the mountains of east Tennessee, where as much as 7% of the population survived the especially frigid winter of 1993-94. Says Lockley: "It's just amazing how adaptive they...
