Today brings: VAMPISAURS! Ok, not really, but it IS about nocturnal predatory dinosaurs.

Paleontologists have generally believed that dinosaurs were active only during the day, preserving their energy at night, when mammals hunted and ate. But an analysis of dinosaur eye structure shows that at least some dinosaurs functioned quite capably in the dark.

Scientists looked at the eye structure of 33 dinosaurs, and "nine of the species, all small carnivores, had eyes that were characteristic of living nocturnal animals".

But we already KNEW that... I mean that dilophosaurus killed Nedry at night. Actually all the good predatory scenes took place at night. So yeah. More here and here.

Thanks, Slog-tipper Brad!
