People were just as skeptical about Australian Jurassic labyinthodonts
(to the point where researchers tried to redate the Siderops deposits to
the Triassic to make people happy). Then Jurassic laby's were found in
China as well as Australia, and they were grudgingly accepted.
Along came Cretaceous laby' remains, and the skepticism returned.
There's nothing scientists hate more than when evidence seems to smash
the crystal spheres of their nice neat theories - and yet there's
nothing better for the advancement of science itself. If only the
universe was the ordered, logical place that humans wish it was!
