Inch Long Fleas

Dinosaurs also had to deal with the pest of the fleas, that were an inch long.  The oldest fleas ever found sucked dinosaur blood from 125 million to 165 million years ago. A new fossil was found in China by the Institute of Geology and Paleontology.  Diying Huang says that their disproportionately long proboscis, or straw-like mouth, had sharp weapon-like serrated edges that helped them bite and feed from their super-sized hosts, he and other researchers reported Wednesday in the journal Nature.  The ancient female fleas were twice the size of the male, this is also the case for current fleas.
