Do we have dromaeosaurid evolution backward?
In the spirit of my past posts on ceratosaurian ornithomimosaurs and an
ornithischian-theropod group, I just uploaded a blog entry which entertains
another heterodox phylogeny. This time it's something relevent to recent
Xiaotingia and neoflightless conversations on the list. What if the Paulian
idea of neoflightless dromaeosaurs is completely wrong? Not only was the
ancestral paravian flightless, what if the outwardly carnosaur-like
Achillobator and Untahraptor represent the most basal dromaeosaurids, and
indeed the entire coelurosaur stem were carnivores of coelurid-compsognathid
grade? Is there any evidence for such an idea? Has a transitional form been
known for over a century?
