U.S. researchers have discovered a rare 46 million years old Fossil mosquitoes. “It is the first fossil of a mosquito, which is still soaked with blood,” said the lead author of the U.S. scientific journal Proceedings of the National Academy of Sciences published study, the biochemist Dale Greenwalt from the Museum of Natural History in Washington. The blood can come from a bird, but this is pure speculation, because of the fossil is no more DNA’ll win.

The oldest ever discovered mosquito fossil is more than twice as old, but contains no traces of blood, Greenwalt said. Means of mass spectrometry, an increased iron content in the fossil detected which is due to blood molecules. The lost piece comes from the collection of an entomologist Travelers who discovered the fossil 25 years ago in the U.S. state of Montana.
