Fossil Sites

Below are links to scoresheets for assemblages that have been dated as Paleogene. The Reference/Source column indicates publications and/or museum collections that form the basis of the scores. The latitudes and longitudes are derived from data provided by the Berkeley UCMP collections database or the original reference. The Assumed Age is the age used to determine the Palaeolatitude (PLat) using PointTracker 4.5 software supplied by Chris Scotese.
