Well, not that I have checked, but perhaps they can tell that specimen A is older than specimen B by a significant amount due to the stratigraphy of the specimens, even though they can't say how old specimen A or specimen B is with any great precision.
Sorry, microraptor (covered in the nova story) dates from the early Cretaceous, well after Archaeopteryx. This new find dates from the late Jurassic but pre-dates Archaeopteryx finds. This fossil was just found this year. Not every four winged dinosaur with feathers is the same. Jeeze.
