Is the Anthropocene an issue of stratigraphy or pop culture

We thank Jan Zalasiewicz and his colleagues for their thoughtful review and critique of our comment on the stratigraphic relevance of the term Anthropocene. We agree that broad and open discussion is useful; however, we wish to clearly iterate that we are not taking a position as flag bearers for the anti-Anthropocene side of the debate. We simply wish to offer our concerns about the formal adoption of the Anthropocene into stratigraphic practice and its growing interplay with the environmental movement at large.

ABSTRACT: Sequence Stratigraphic and Paleoecologic Lowstand Model of Ephemeral Connections in Epeiric Seaways, U.S. Western Interior Cretaceous

High-resolution sequence stratigraphy of mid-Cretaceous (Albian-Cenomanian) strata in the U.S. Western Interior between Wyoming and Texas reveal that rocks generally attributed to transgression during the early part of the Greenhorn third-order cycle record three thin sequences of unusually large regional extent deposited during three lower-order marine cycles. The three sequences are best exposed in the Oklahoma Panhandle section of the Dakota Formation.
