Fossilized Mosquito Has Blood-filled Abdomen

ananyo writes "Jurassic Park's iconic image of a fossilized blood-filled mosquito was thought to be fiction — until now. For the first time, researchers have identified a fossil of a female mosquito with traces of blood in its engorged abdomen. The fossilized mosquito contains molecules that provide strong evidence of blood-feeding among ancient insects back to 46 million years ago (paper abstract). The insect was found not in amber, as depicted in Jurassic Park, but in shale sediments from Montana. After 46 million years, however, any DNA would be long degraded."

    That's what they used to say about Neandertal DNA. Turns out the DNA does indeed begin to fragment but you can still piece it together for a very long time after it begins to degrade. In this case that statement is it's probably right and 46 million years is too long and even if you could recover some Dino DNA (from any source) it will be fragmented beyond recovery with current technology. Even so, we should not stop trying to defy established notions of what is impossible. A Scientist at Yale University recently discovered that pigments do not degrade, they sometimes fossilise which is an amazing discovery since it means that if we find fossilised dinosaur skin, feathers or insect exoskeletons for that matter we can figure out what color long extinct animals were. It was almost a scientific axiom that we would never know what color dinosaurs were and it certainly blew me away when I found out that was wrong.

      true but it is curious as to what kind of animal it dna of. While the earth would have restored itself. There were no dinosaurs, so i wonder what kind of creature that blood sucker liked to feed on.

      They all can. Gender in amphibians and reptiles is largely determined by the ambient temperature of the eggs.
      This is unlike mammals and birds where mostly predetermined by genetics (sex chromosome).

    The real bottom line is that we should be searching for cold spots, like Antarctic caves, with relict animal DNA that might average -57C (-70F). Then let's see how many million years we can drive DNA recovery.
