NOWAK, MICHAEL D.* and JOHN D. CURTIS. Biology Department, University of Wisconsin - Stevens Point, Stevens Point, WI 54481. - New and Problematic Taxa from the Almont, North Dakota Locality (Late Paleocene).
In 1990 Crane, Manchester, and Dilcher published a preliminary
monograph outlining the remarkably preserved late Paleocene flora from
the Almont, North Dakota locality. In this monograph approximately 60
percent of the taxa were of unknown affinity, and the precise
stratigraphic position of the material was unclear. In the last 12
years research and collection efforts have lead to the identification
and/or reevaluation of several of these taxa, and acquisition of taxa
not in the monograph. We will display a number of undescribed seeds,
fruits, flowers, and leaves from this site, in addition to several
taxa whose affinities have been clarified. Preliminary pollen analysis
of the Almont locality indicates it lies within biozone P5 of the late
Paleocene, based on Nichol’s biostratigraphic zonation of the
Williston Basin.
