That's pretty awesome, but it requires so many ghost lineages!Zachhttps://www.blogger.com/profile/08692080707969333711noreply@blogger.comtag:blogger.com,1999:blog-5519292617097628087.post-44130754808465456692009-06-29T06:11:42.088-07:002009-06-29T06:11:42.088-07:00From the paper:

As the precise age of Eshanosaurus has profound implications for understanding the timing of the coelurosaur radiation, additional collecting and stratigraphical work is needed at the type locality in order to confirm or refute its Early Jurassic age. In the meantime, the potential importance of Eshanosaurus should be assessed critically and its unprecedented stratigraphical position should not be used as a criterion for excluding this taxon from analyses of coelurosaurian and theropod evolution."Thomas R.
