Well if Dave says it, then it must be true, right? I might as well delete
my unfinished manuscripts, return my borrowed specimens, and resign my
academic position because my interest in evidence is unnecessary when we can
rely instead on authority. If Dave is the pterosaur authority, then who is
the comparable dinosaur authority? Holtz? Bakker? Sereno?
