R. Michael Easton, born in Toronto, has been a geologist with the Ontario Geological Survey since 1982, after studying at the University of Western Ontario (B.Sc. 1972), University of Hawaii, (M.Sc. 1976), and Memorial University of Newfoundland (Ph.D. 1982). He specializes in Proterozoic geology, with an emphasis on chronology, stratigraphy, and mapping. He is the author and coauthor of more than 60 geological maps and 150 papers. He was also the 1996 chair of the North American Commission on Stratigraphic Nomenclature (NACSN).James O. Jones (1935–1999) obtained his B.Sc. degree in geology from Midwestern State University in 1962; his M.Sc. degree from Baylor University in 1964; and his Ph.D. in geology from the University of Iowa in 1971. He first taught at Southern Arkansas University, but spent most of his career, from 1977 onward, at the University of Texas at San Antonio. He retired from the U.S. Army Reserve as a lieutenant colonel in 1995. He was the 1997 chair of the NACSN.

Alfred C. Lenz spent most of his career teaching paleontology and stratigraphy at the University of Western Ontario, where he is now an emeritus professor. His primary research interest is the study of graptolites. He was the 1998 NACSN chair.

Ismael Ferrusquía-Villafranca, born in Mexico City, obtained his B.Sc. degree in biology from Universidad Mexico in 1964 and his M.Sc. degree in paleontology in 1967 and his Ph.D. in geology in 1970, both from the University of Texas at Austin. He is a senior scientific researcher at the Instituto de Geología, Universidad Nacional Autónoma de Mexico. He is the author and coauthor of more than 160 publications on the geology and vertebrate paleontology of Mexico. He was the 1999 NACSN chair.

Ernest A. Mancini is the regional director of the Eastern Gulf Region of the Petroleum Technology Transfer Council, the director of the Center for Sedimentary Basin Studies, and Distinguished Research Professor in petroleum geology, Department of Geological Sciences, University of Alabama. His research focus is on reservoir characterization and modeling, petroleum systems, and the application of stratigraphic analysis to petroleum exploration. He was the 2000 chair of the NACSN.

Bruce R. Wardlaw is chief paleontologist at the U.S. Geological Survey in Reston. His interests include the study of Permian conodonts and stratigraphy and coastal environmental geology. He was the 2001 NACSN chair.

Lucy E. Edwards has been a research geologist with the U.S. Geological Survey in Reston since 1977. Her specialties are coastal-plain stratigraphy; dinoflagellate biostratigraphy; Cretaceous and Cenozoic stratigraphy, correlation, calibration, and nomenclature; quantitative stratigraphy and graphic correlation; stratigraphic nomenclature and classification; and impact stratigraphy and taphonomy. She has chaired the NACSN twice.

Brian R. Pratt has been a faculty member at the University of Saskatchewan since 1989 after studying at McMaster's University (B.Sc. 1976), the Memorial University of Newfoundland (M.Sc. 1979), and the University of Toronto (Ph.D. 1989). He keeps one foot planted in paleontology and the other in sedimentology and counts himself a stratigrapher, concentrating on the Precambrian and lower Paleozoic rocks of western and northern Canada. He was the 2003 NACSN chair.

	NOTE 65: RECORDS OF STRATIGRAPHIC COMMISSION, 1995–2002

 
Note 65 summarizes the activities of the North American Commission on Stratigraphic Nomenclature (NACSN) from November 1995 to October 2002 and is condensed from the minutes of the NACSN's 50th to 57th annual meetings (available upon request from the NACSN archivist N. P. Lasca, Lapham Hall, 3209 North Maryland Avenue, University of Wisconsin, Milwaukee, Wisconsin 53211.) The NACSN activities can be divided into four main categories: (1) activities related to revising the North American Stratigraphic Code; (2) committee work, (3) interaction with other groups; and (4) outreach activities related to the discussion and promotion of the science of stratigraphy and the application of the North American Stratigraphic Code.

	AMENDMENTS TO THE NORTH AMERICAN STRATIGRAPHIC CODE

 
The current version of the North American Stratigraphic Code, hereafter referred to as the Code, was published 20 yr ago. (NACSN, 1983). One of the functions of the NACSN is to periodically review the Code to ensure that it meets the present and emerging needs of the profession. This is done through consideration and publication of proposed amendments to the Code, as provided for in Article 21.

Note 63 (Application for amendment of the North American Stratigraphic Code concerning consistency and updating regarding electronic publishing) and Note 64 (Application for revision of Articles 48–54, biostratigraphic units, of the North American Stratigraphic Code) were accepted with minor revision at the 57th annual meeting of the NACSN in 2002.

Note 63 included updating of Article 4 of the Code concerning publication using electronic media as well as allowing for the electronic publishing of new stratigraphic units. The revision to Article 58 (Allostratigraphic Units), as suggested in Note 63, contained an inconsistency that was detected during the 1-year public-comment period that is required between the publication of the note and the vote on approval by the NACSN.
