The current issue of Palaeontologica Electronica published a paper on New Geochronologic and Stratigraphic Evidence Confirms the Paleocene Age of the Dinosaur-Bearing Ojo Alamo Sandstone and Animas Formation in the San Juan Basin, New Mexico and Colorado.

This isn't a new discovery, but the careful analysis of the magnetostratigraphy, palynology, and sedimentology is, and it strengthens the case for some dinosaurs (relatively) briefly surviving the Cretaceous-Tertiary extinction in some areas.

I haven't read the paper in excruciating detail yet (end of the semester, ack!), but I will post some more thoughts on it later. For now, if there are any other paleo geeks here, I'd love to hear your thoughts!
