Researchers have found a fossil of a female mosquito embedded in shale sediments in Montana.  The abdomen of the mosquito is bloated with blood that is believed to be almost 46 million years old.  Even though the researchers say the DNA in the blood has long since disintegrated, there are still large traces of iron and porphyrin, both of which make up hemoglobin.

So unfortunately, they can’t extract the DNA and use it to grow dinosaurs.  Bummer.  I wanted to ride a pterodactyl.  But still.  Pretty cool.
