These's a billion dollars industry behind the dinosaurs which is in its best interest to keep these "research" daily updated to not stay stale and to satiate the masses. Unless an unquestionable proof exists these research papers are at most ink on paper.
I used to love dinosaus when I was young but now eventhough I still like them somewhat a bit but as neat thing nothing more and I have big doubts about them.
Just dig about them when they first discovered and you'll see what I'm talking about. The whole deal is very sketchy.
