Paleogene Dinosaurs ???

A new paper about the direct dating of dinosaur bones,
has been published online in advanced of its publication 
in “Geology.” It is:

Fassett, J. E., L. M. Heaman, and A. Simonetti, 2011, Direct 
U-Pb dating of Cretaceous and Paleocene dinosaur bones, 
San Juan Basin, New Mexico. Geology, first published 
on January 5, 2011,  doi:10.1130/G31466.1

http://geology.gsapubs.org/content/early/2011/01/05/G31466.1.abstract

Based on such dating, they argue that within the area of what
is now New Mexico, dinosaurs survived the K-P impact and
became extinct within the Paleogene.
