Did mosquitos kill the dinosaurs?

An alternate theory holds that dinosaurs died of embarrassment: A Fredrogersaurus, obviously wishing he were dead, extinct, or just anywhere but here.

Biting insects spread all kinds of diseases. (You can learn all about this in the Science Museum’s newest exhibit, Disease Detectives.) Now a scientists thinks they may have also helped kill off the dinosaurs. George Poinar, a professor of zoology at Oregon State University, notes that many insects from dinosaur times have been preserved in amber. Many of them carry microbes that can cause malaria, dysentery and other illnesses. He speculates that these illnesses could have been the major cause of the dinosaurs’ long, slow demise. The asteroid impact / volcanic activity / climate change simply finished them off.

Poinar and his wife Roberta have published a book, What Bugged The Dinosaurs? Insects, Disease And Death In The Cretaceous. In it they also note that, late in the dinosaur era, flowering plants spread rapidly, helped along by newly-evolved insect pollinators. This sudden change in available food may have also played a hand in the dinos’ extinction.

I never reallly thought about the bugs killing out the dinosaurs, but i guessyou should never under estimate the power of the insects! (: Haha ! they have been around for millions of years, so i guess it is infact a very plain old possibility. It has just as many facts to back it up as the other theories!

It's not so much the bug, as it is the germs the bug carried.

I do not believe the mosquitos killed the dinosaurs since there is no fossil evidence of A DEAD MOSQUITO. They could of killed of one or two or the T-Rex because when they fall down they won't be able to pick themselves back up again. But it is totally impossible that a minuscule insect such as the mosquito can kill off a whole species. :)

Try googling "fossil mosquito." You'll find that there have been many discovered, dating back to the time of the dinosaurs.

Tiny germs can devastate populations. Added to other stress factors, mosquitoes could have easily contributed to the dinosaurs' demise.

I thought the astroid or the meteorite that killed the dinausors but the mosquito killing is a big possibility so I believe that all three could have killed the dinausors
