Castorimorpha is the suborder of rodents containing the beavers and the kangaroo rats. Castorimorpha comes from the rodent family which then breaks into a mouse related clade. From the mouse related clade three different branches developed: castorimorpha (consisting of the beaver and kangaroo rat), anomaluromorpha (consisting of scaly-tailed squirrel and springhare), and myodanta (consisting of jerboa, the muridea mouse and blind mole rat).[1] This classification is a reconstruction of the rodent's phylogenetic relationships based on retroposon screening. Reconstruction of the rodent's phylogentic relationship also looked at the rodent's jaw structure.[1]
