TAXONOMIC STANDARDS:
Genus
and species names for large mammals, and
biochronologic occurrences from earlier papers, were updated
to conform to:
Janis,
C. M., K. M. Scott, and L. L. Jacobs (eds.) 1998. Evolution
of Tertiary Mammals of North America. Cambridge University
Press, New York.
If
a later publication superceded the taxonomy or biochronology
used in the Janis et al. volume, the more recent taxonomy or
biochronology was used. Because of the continuing uncertainty
in naming oreodonts, in most cases oreodont taxonomy remained
that proposed by Lander (1998 in the Janis et al. volume).
Genus
and species names of rodent taxa were
initially updated to conform to:
Korth,
W. W. 1994a. The Tertiary Record of Rodents in North America.
Plenum Press, New York.
If
a later publication superceded the taxonomy used in the Korth
book, the more recent taxonomy was used.
The
initial taxonomic standard above the species level was:
McKenna,
M. C. and S. K. Bell. 1997. Classification of Mammals Above
the Species Level. Columbia University Press, New York.
When
more recent literature provided updates, the more recent designation
was used.
