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.
