Scientists have found fossils of huge fleas that dined on dinosaur blood.  Modern fleas are about 1-10 mm in length, but Cretaceous fleas were between 8-21 mm (not really big, but a 21 mm flea would devour your pet dog quickly).  Also they have armored jaws, apparently to dig into dinosaur hide.

So the next time you watch Jurassic Park, think of those giant fleas that show up!
