This "most recent common ancestor" would have to be the sister group to all
other dinosaurs, as Triceratops and birds represent the two large clades of
dinosaurs. Definitely not Eoraptor. Lagosuchus or a close relative,
perhaps? But then lagosuchids ("lagosuchians?") are excluded from
dinosauria, aren't they?
I'd appreciate any reference on Marasuchus.
