Monster fleas sucked the blood of Jurassic dinosaurs


It seems that dinosaurs weren’t the only scary monsters of the Jurassic period as newly-discovered fossils reveal giant blood-sucking fleas afflicted the prehistoric world.

Scientists say that the 2cm-long parasites, which roamed the planet between the Middle Jurassic and Lower Cretaceous, were up to four times larger than their descendants - the fleas we see today.
