Re: [dinosaur] Cenomanian-Turonian dinosaur extinction



Sampling of dinosaurian faunas of the late Cenomanian and Turonian is spectacularly poor. So no, we can't state anything definitively about diversity changes at that boundary.

Good day,

I would like to ask if there is any conclusive fossil record showing that there was a decline in dinosaurian biodiversity during the transition between the Cenomanian and Turonian stages? Thank you in advance, Tom
