[...] Our results also confirm that Juramaia is anomalous in exhibiting a much more derived morphology than expected given its age, which in turn implies very high rates of evolution at the base of therian mammals.

I would rather say it adds to the evidence that Juramaia isn't from the Yanliao Biota at all, but from the Jehol Biota, and really is Early Cretaceous in age.

For a review of that topic, see section 2.1.17 in this open-access preprint of mine.
