Cryptodontia is a group ofdicynodonttherapsids that includes the familiesGeikiidae,Oudenodontidae, andRhachiocephalidae. It was first named in 1860 by English paleontologistRichard Owen. Owen intended Cryptodontia to be a family, and the name was later changed to "Cryptodontidae" to reflect this ranking. The name Cryptodontia was restored in 2009 when it was redefined as a largerclade containing several families of dicynodonts.[1]
