Re: Body Size Evolution in Mesozoic Birds

...

Contrary to previous interpretations of early avian evolution, we demonstrate an overall increase in body size across Jurassic and Cretaceous flying birds: taxon body size increases from the earliest Jurassic through to the end of the Cretaceous, across a time span of 70 Myr.

Um, what "earliest Jurassic" flying birds are they talking about here? Or do they mean latest Jurassic (which would also fit better with the 70 Myr time frame)?
