Abstract

A sample of 2,360 skulls representing 21 of the 22 recognized species of Dipodomys were examined for the presence and structure of the interparietal. The interparietal is basically formed from four ossification centers. These often fuse during the early stages of development. The median components are the equivalent of the interparietal of other animals while the antero-lateral components are possibly equivalent of the tabular bones of reptiles and primitive mammals.
