An exclusive 46-million-years old
mosquito fossil with a belly full of dried blood has been discovered in a
Montana riverbed, according to United States researchers. It is an extremely infrequent
fossil, the only one of its kind in the world," Dale Greenwalt, lead
author of the study in the Proceedings of the National Academy of Sciences
(PNAS), said. Mr Greenwalt said it might have been blood from a bird, since the
ancient mosquito look like a modern one from the genus Culicidae, which likes
to feed on bird.
