We all know the story - dinosaurs were supposedly wiped out by an asteroid over 65million years ago. However, it is now being suggested that it could have been disease-spreading mosquitoes and other biting insects that lead to their demise.

By the most conservative measure - based on the last century's recorded extinctions - the current rate of extinction is 100 times the background rate. But many scientists estimate that the true rate is more like 1,000 to 10,000 times the background rate.

The earth experienced its biggest mass extinction about 250 million years ago, an event that wiped out an estimated 95% of marine species and 70% of land species. New research shows that this mass extinction fundamentally changed the basic ecology of the world's oceans.

British researchers have hit on a clever way to search for ancient ozone holes and their relationship to mass extinctions: measure the remains of ultraviolet-B absorbing pigments ancient plants left in their fossilized spores and pollen.

A study of fossils from the Paleozoic Era, collected across the world, reveals that ancient brachiopods were little bothered by predators. However, the rare predation traces left on brachiopod shells by unknown assailants coupled with a subtle increase in their frequency through time may be the shadows on the wall that show killers were in the room and their numbers increased with time.
