Predator dinosaurs may have been night-hunters

Following on the heels of the discovery of a new dinosaur species, another interesting piece of research has come out about these prehistoric monsters: Many carnivorous species were nocturnal.

The study, published in the journal Science, casts doubt upon the idea that hundreds millions of years ago (up until about 65 million years ago), most dinosaurs were active only during the day, leading mammals to hide from them in the shade. In fact, several carnivorous dinosaur species were probably sleeping during the day, and would hunt at night, new research suggests.

"It gives us a new view of how to reconstruct the dinosaur era and how the environment in the Mesozoic, the dinosaur era, was actually used," said Lars Schmitz, a postdoctoral researcher in the Department of Evolution and Ecology at the University of California, Davis, and co-author of the study. "That's a totally new component of paleontology."
