Dinosaur Bone-Bearing K-P Tsunami Deposits, La Popa Basin, Mexico

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:
