It's an Eocene mosquito. Dinosaurs were already extinct. Notable about this period is it was the last time there was no ice at the poles and water covered a lot more of the earth, as you can see from the map of the Eocene: https://en.wikipedia.org/wiki/Eocene which means there were probably a lot of blood-filled mosquitos around during the Eocene.
Also from the article: DNA has a half-life of ~521 years so there's no DNA left in the blood.
