Fossilized track marks from a stampede of dinosaurs in Australia actually may have come from swimming animals, new research suggests.

The finding, published in the January issue of the Journal of Vertebrate Paleontology, upends the traditional interpretation of the world’s only dinosaur stampede. . . . Read Complete Report

Millions of years ago, oversized insects like griffinflies boasting wingspans comparable to today’s hawks scuttled across (and fluttered above) the planet. But why these jumbo jets of the insect world shrunk to modern size has remained a mystery, until now.
Turns out, as dinosaurs evolved flight and eventually took to the skies as birds, they beat down the huge insects already living there, effectively putting a cap on insect size through predation and competition in the prehistoric skies, as birds developed into sophisticated flying machines. . . .Read Complete Report

For some time now, scientists have assumed that dinosaurs’ tails didn’t simply drag on the group behind them, but were instead held out to serve as a counterweight for the giant reptiles’ heavy front ends when running. More recently, however, researchers from the University of California, Berkeley, have discovered that modern-day lizards also use their tails to control the orientation of their bodies when leaping through the air. It’s a discovery that could be applied to devices such as search-and-rescue robots, and in fact already has been. Based on their observations, the UC Berkeley team created a small, tailed robot known as Tailbot. . . read complete report
