Jurassic Park Flea Style

Paleontologists excavating in eastern China recently discovered perfectly preserved fossils of fleas.  The fossils are thought to be 125-165 million years old. This outdoes the current oldest fossil record by 60 million years.  This discovery gives scientists clues as to how the fleas fed on their prey.  These ancient fleas were not only giant, but also wingless.  The fossilized fleas were about two times larger than modern fleas.  In addition to their winglessness the fleas also did not have back legs, which leads scientists to believe that they fed on their prey by hiding in the skin.  They also had serrated jaws as apposed to smooth siphons.  These giant fleas are one of the many discoveries that are helping scientists learn about early life forms.http://the-scientist.com/2012/03/01/jurassic-parasites/
