The internal skeleton of the nasal cavity is sporadically and often incompletely described for many marsupial species and mammals in general. Here, I provide an anatomical survey of the ethmoid in the skulls of adult marsupials based on examination of computed tomography (CT) imagery of 29 taxa representing all the major extant groups of marsupials. (…) I compared ecological data with the number of ecto- and endoturbinals as a preliminary test to determine whether some of the interspecific variation in the osteology of the ethmoid is a result of ecological factors, but found few correlations to support this idea.
