| Stratigraphy comments: No forams have been recovered from this unit, it is assigned to the Gansserina gansseri zone by Mancini et al. (1996) by sequence stratigraphy and the biostratigraphy of surrounding units. Haustator bilira assemblage zone. PJW: Nyborg et al. provide updated stratigraphy that restricts Chiwapa to Racemiguembelina fructicosa/CC25/Discoscaphites conradi zones. | |||||
