Submission + - Fossilised mosquito has blood-filled abdomen (nature.com)

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 mosquitowith 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.
