MNA V8415, Blue HillsZanno L. E., Heckert A. B., et al (2002)Chinle - Blue MesaGiven as low in the Blue Member of the Petrified Forest Formation = Blue Mesa Member of the Chinle Formation. Adamanian LVF, suggested to be late Carnian, but recent radiometric dates indicate a Norian age for the Chinlemudstone228 - 208.5 Ma
