Old world ruminant morphophysiology, life history, and fossil record: exploring key innovations of a diversification sequence
646.07 KB 0 downloads
Abstract: The omasum of pecoran ruminants (which is absent in tragulids) and shorter gestation periods in non-giraffid crown pecorans (as opposed to giraffids) could represent cases of key innovations that caused...
