It is no mosquito. It is a tick (they still look gross to me), but the fossil is a very cool find. Sadly no recoverable DNA this time though.
I always thought it was entertaining to think about the Jurassic Park movie and creating dinosaurs from DNA discovered in amber. If the process did work, the genetic makeup of the animals was adapted to a 30% oxygen environment. If the created dinosaurs could survive at all, they certainly would not be able to hunt humans.
This would not make a very good movie.
