• coordinate based on nearby landmark
When: Poortjie Member (Teekloof Formation), Capitanian to Capitanian (264.3 - 254.2 Ma)
• Beaufort West Commonage was listed as Cistecephalus Assemblage Zone in Kitching, 1977 (and was referred previously as Endothiodon Assemblage Zone) before the definition of the Tropidostoma Assemblage Zone (see Rubidge & Keyser, 1995). Posterior works, as Kammerer et al., 2011, identify fossils from this locality as pertaining to the both the Tropidostoma and the Cistecephalus Assemblage Zones.

•Direct dates for the Tropidostoma and Cistecephalus Assemblage Zones from Rubidge et al., 2013
• bed-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
Size class: macrofossils
