Title: Stratigraphic Significance of Uvigerinid Foraminifers in Western Hemisphere: ABSTRACT

Author(s): James L. Lamb, Theo H. Miller

Article Type: Meeting abstract


Uvigerinid foraminifers increasingly are recognized as particularly useful paleobathymetric indices, and current data also provide easily applied bases for their use in biostratigraphic interpretation. Thus, use of many forms of the family Uvigerinidae occurring in the Western Hemisphere can expand utilization of these important forms and provide uniformity in nomenclature and classification.

Uvigerina and related genera illustrate lineage concepts and facilitate paleobathymetric considerations. These biostratigraphic interpretations, based on life ranges of commonly occurring benthonic species, are applicable widely in areas lacking the critical warm-water planktonic organisms normally used in dating.

The genus Tiptonina (type species Siphogenerina nodifera) and the species Uvigerina praehubbardi are proposed as new.
