The 'Birds Come First' hypothesis of dinosaur evolution

The 'Birds Come First' hypothesis of dinosaur evolution

Here, we look at a rather different proposal: the decidedly non-standard, non-mainstream Birds Come First (or BCF) hypothesis proposed by George Olshevsky. Bird-like maniraptorans (deinonychosaurs and so on) are younger than basal birds, not older than them as they should be if birds evolved from deinonychosaur-like ancestors.
