Oudenodon grandis

Anomodontia - Cryptodontidae

Discussion

The status of Oudenodon grandis is regarded as "uncertain" by Kammerer et al., 2011: "We tentatively consider “D.” grandis to be a distinct species of giant cryptodont, but refrain from any generic assignment pending further study. Whether SAM-PK-2679 represents a gigantic individual of Oudenodon bainii, an aberrant rhachiocephalid, or the sole known representative of a separate cryptodont taxon remains to be determined"

Taxonomy
Dicynodon grandis was named by Haughton (1917). Its type specimen is SAM-PK-2679, a skull, and it is a 3D body fossil. Its type locality is Dunedin, which is in a Wuchiapingian terrestrial horizon in South Africa.

It was synonymized subjectively with Oudenodon bainii by Kitching (1977); it was recombined as Oudenodon grandis by Van Hoepen (1934), Keyser (1975), Brink (1986) and King (1988).
