geomyidae การใช้

Among extant rodents, only the families Sciuridae, Castoridae, Heteromyidae, and Geomyidae are truly sciuromorphous.
Pocket gophers are of the order Rodentia, and of the Geomyidae family, they are sister to the new world Heteromyidae.
Some authorities would exclude the Geomyidae and Heteromyidae from that list due to the attachment of the medial masseter directly behind the zygomatic arch.
Like a number of other ground squirrels, they are sometimes called " "'gophers " "', though this name belongs more strictly to the pocket gophers of family Geomyidae.
