Species: browni BROOM, 1906
Etymology:
Holotype: SAM-PK 5871
Locality: Aliwal North, Eastern Cape Province, South Africa.
Horizon: Burgersdorp Formation, Tarkastad Subgroup.
Biostratigraphy: Cynognathus zone.
Age: Spathian Stage, uppermost Scythian Epoch to Anisian Stage, lowermost Mid Triassic Epoch, Early to Middle Triassic.
Material: Fragmentary dentary.
Note: Broom (1906) placed Palacrodon in Rhynchocephalia; Malan (1963) disagreed and suggested it was either a lizard or procolophonid. Gow (1999) synonymized Fremouwsaurus geludens (Gow, 1992) with Palacrodon. Kligman et al. (2018) place it within Diapsida.
