Comparative Anatomy and Systematic Implications of the Turbinal Skeleton in Lagomorpha (Mammalia)
ABSTRACT In order to elucidate the systematic relevance of the turbinal skeleton in Lagomorpha the ethmoidal regions of 6 ochotonid, 21 leporid, and 2 outgroup species ( Sciurus vulgaris , Tupaia sp.) species were investigated by high‐resolution computed tomography (μCT). Number and shape of turbina...
