Figure 17
Premolar foramen distribution in extant Lagomorpha.
A. All living genera, supertree from [25], modified. B. Lepus and Sylvilagus, tree from [23]. Black, the foramen present in all examined specimens; white, absent in all examined specimens; gray indicates presence in some specimens; ? denotes uncertainty about homology of the opening.
