Exceptionally preserved invertebrate fauna from the Upper Cretaceous Paguate Member of the Dakota Formation, Rio Puerco Valley, New Mexico
Paul L. Sealey and Spencer G. Lucas
We document a very well preserved bivalve and gastropod fauna associated with Acanthoceras amphibolum Morrow in the Paguate Member of the Dakota Formation on the western side of the Rio Puerco northwest of Albuquerque, New Mexico. This fauna includes Pycnodonte cf. P. kellumi (Jones), Exogyra trigeri (Coquand), cf. Phelopteria aguilerae (Böse), Legumen ellipticum Conrad, Ostrea sp., Granocardium enstromi (Bergquist), Idonearca blanpiedi Stephenson, and Turritella cf. T. shuleri (Stephenson). Other than a single specimen of Turrilites acutus americanus Cobban & Scott, all other ammonites collected are A. amphibolum. These fossils are from the A. amphibolum Zone, which is of middle Cenomanian age.
