Allophaiomys and the Age of the Olyor Suite, Krestovka Sections, Yakutia

摘要

The report was written to illustrate how the biochronology of the microtine genusAllophaiomys, and those genera derived from this genus, is complex and asynchronous on a global scale, and also to demonstrate how the interpretation of the age of any fossil locality that is based upon this biochronology cannot be convincingly made across provincial boundaries without knowledge of the history of these lineages within each province of concern. However, with this knowledge or within a single faunal region, it is shown that a biochronology can be developed with a temporal resolution that approximates a precision of 5,000 years.
