Clade of bidentalian dicynodonts
Elphidae is a clade of bidentalian dicynodonts containing Elph , Katumbia , and Interpresosaurus .[ 1] [ 2] It is exclusively known from the Late Permian of Russia and Tanzania. Elphidae is variously recovered as either at the base of a paraphyletic Cryptodontia ,[ 2] or as basal dicynodontoids .[ 3]
The clade Elphinae was erected by Kurkin (2010) to pertain to a clade containing Elph and Interpresosaurus , two dicynodonts from Late Permian Russia. This clade was diagnosed by a sharply shortened preorbital skull, relatively small tusks located below the anterior orbit, and maxillae with depressions located below the naris.[ 4] Elphinae is often recovered forming a clade with the Tanzanian Katumbia ,[ 1] to which the name Elphidae can be applied under the rules of the ICZN .[ 2]
