. Many authors have suggested that the two extant families may be only distantly related, and that they belong to separate suborders or infraorders. For example, the Pedetidae are the only family of rodents with multiserial enamel except for the HystricognathiHystricognathi Overview

. This character, the hystricomorphous zygomatic region, and a common distribution in southern continents has led many researchers to suggest that the springhare (but not anomalures) may be allied with hystricognaths.
