Wednesday, July 30, 2014 – A new find and study extends the known lineages of true bugs by approximately 30 million years, into the early Cretaceous period. Three true bug fossils were found to contain a significant amount of iron, suggesting they drank blood, though which dinos (or birds, or mammals) the true bugs fed on is unknown.

The abstract can be found in Current Biology, and a brief article at New Scientist.
