Stratigraphy
Formation: | Annero | Member: | Vitaback Clay | ||
Local section: | Vitaback Clays | Local bed: | VC3 | ||
Stratigraphy comments: The lowermost parts of the section (beds VC1 and VC2) contained spores of the genus Cicatricosisporites, previously known only from the Early Cretaceous (V. Vajda pers.comm.). Thus, the whole section described in this work is considered to be Berriasian or possibly younger, although the lower parts of the VitabaÈ ck Clays, not treated here, are likely to be Tithonian (ErlstroÈm et al. 1991). Berriasian age is further indicated by the composition of the shark fauna, which is very similar to that of Berriasian sediments within the Purbeck Group in southern England (Underwood & Rees 2002). |
Lithology and environment
Primary lithology: | lithified claystone |
Secondary lithology: | lithified siltstone |
Lithology description: The Vitaback Clays primarily include alternating clay and silt deposits (ErlstroÈm et al. 1991). Layers of sand occur less frequently, often as thinner beds. | |
Environment: | lacustrine - small |
Geology comments: The faunal and floral composition was studied by ErlstroÈm et al. (1991), who suggested brackish and freshwater environments with occasional marine influence. |
Taphonomy
Modes of preservation: | body |
