Maps were created by plotting the traces of the seaway from various times in the Cretaceous and plotting the type localities for the same times on the Tapestry map, which showed areas that have been heavily sampled.
One extra benefit of this work is verifying accuracy of the paleogeographic maps within the known age ranges of the type localities.
Since 1963, Navajo Mine strip mine operations have provided coal to the Four Comers Steam Plant, which resulted in the loss of Stanton's
type localities and other Bauer fossils.
The genus Asiotmethis should be revised, using not only museum material, but also new material to be collected from the
