Dear List Members, A recent paper has an interesting description and discussion of K-P tsunami deposits that contain dinosaur bones and impact ejecta. These deposits are part of the Delgado Sandstone Member, which is exposed in the La Popa Basin in north-eastern Mexico.
The paper is: Schulte, P., J. Smit, A. Deutsch, T. Salge, A. Friese, and K. Beichel, 2011, Tsunami backwash deposits with Chicxulub impact ejecta and dinosaur remains from the Cretaceous– Palaeogene boundary in the La Popa Basin, Mexico.
