- Rhynchosauria: biozone with a predominance of Rhynchosaurs (Rhynchosaurs, archosaurs and Cynodonts).
- Traversodontidae: biozone with traversodonts cynodonts (cynodonts and archosaurs).
- Therapsids: Prevalence of Dinodontosaurus and Massetognathus. (Procolophon, dicynodonts, cynodonts, archosaurs and Rhynchosaurs)
- Procolophon: Predominant Procolophon. Much material is fragmented and often difficult to classify. (Temnospondyli, Procolophon, non-mammalian Cynodonts indeterminate and Prolacertiformes indeterminate).
- Pareiasaurus: biozone of Pareiasaurus.
- Mesosaurus: biozone of Mesosaurus.

Famous quotes containing the word geological:
“The crystal sphere of thought is as concentrical as the geological structure of the globe. As our soils and rocks lie in strata, concentric strata, so do all men’s thinkings run laterally, never vertically.”
—Ralph Waldo Emerson (1803–1882)
