No references found			These proceedings from the September 2005 symposium contain research on these very issues and more, including several papers about the life history of species in Pacific waters, more on population structure and speciation, including several genetic studies differentiating data among rockfishes, and two papers on aging and growth including one using radiometric ages. Biology, assessment, and management of North Pacific Rockfishes; ... by SciTech Book News Regarding the youngest chrons, the authors note how, initially, potassium-argon radiometric ages were used, but have been superseded by "absolute orbital-cycle ages with very high precision. A Geologic Time Scale 2004 by Fensome, Rob / Geoscience Canada 1999) used radiometric age determination to confirm the longevity of long-lived species.
