This term was applied by Christensen (1991) to that part of the G. quadrata Zone in southern England that post-dates the A. cretaceus Subzone.
Base: In southern England, the base of the interval is placed at the Whitecliff Flint (Bailey et al., 1983).
Top: In southern England, the top of the interval is placed at the Farlington Marls (Wood, 1995).
Range of index species: There is no index species, the interval equating with strata between the top of the range of Applinocrinus cretaceus and the Farlington Marls.
Key fauna:
Bivalvia: | inoceramid shell debris (locally abundant) |
Belemnoidea: | Belemnitella mucronata |
Gonioteuthis quadrata | |
Echinoidea: | Echinocorys brydonei |
Bio-markers: There are no bio-markers for the lower part of the interval. At the top of the interval, between the Scratchell's Marls and the Farlington Marls, Echinocorys brydonei, Gonioteuthis and Belemnitella co-occur (Wood, WH/95/31R; Bailey et al., 1983).
Age: Campanian
