Pollen Spectra as Time Markers

A few years ago the cranial bones of an extinct moose, Cervalces sp?, were found in th peaty deposits in the valley of Potato Creek, near North Liberty, St. Joseph county, Indiana. A full description of this rare fossil was given by Gazin (1938). The bones are now in possession of the U.S.N.M., No. 15,494. The finder of the skull, Mr. Alton Bernhardt, of North Liberty, collected with the skull some of the soil in which the bones lay embedded and gave it to Dr. Marcus Ward Lyon, of South Bend, Indiana, who in turn sent it to the writer for pollen analysis and a possible determination of the age of the skull.
