Re: Oviraptor

Jaime keeps mentioning the Cenomanian-Campanian boundary...apparently forgetting all about the intervening Turonian, Coniacian, and Santonian Stages. Biostratigraphic correlations are utterly meaningless when based upon taxa that are not CONSPECIFIC. Genera cannot be correlated, families cannot be correlated, ONLY species can be correlated. Thus, correlating Asian and North American faunas is absolutely borad-brush unless the same species are being used. Geochronology is your friend...do not be afraid of it.
