Eodicynodon Assemblage Zone
The Eodicynodon Assemblage Zone is a tetrapod assemblage zone or biozone which correlates to the Abrahamskraal Formation, Adelaide Subgroup of the Beaufort Group, a fossiliferous and geologically important geological Group of the Karoo Supergroup in South Africa. The thickest outcrops, reaching approximately 620 metres (2,030 ft), occur south-east of Sutherland, north of Prince Albert, and south-east of Beaufort West. The Eodicynodon Assemblage Zone is the lowermost biozone of the Beaufort Group.

The name of the biozone refers to Eodicynodon oosthuizeni, a small to medium-sized herbivorous dicynodont therapsid. It is characterized by the presence of this dicynodont genus along with the Nyaphulia, and the dinocephalian Tapinocaninus pamelae.
