The lost paleosols: Masked evidence for emergence and soil formation on the Kimmeridgian Jura platform (NW Switzerland)

Waite, Richard ; Marty, Daniel ; Strasser, André ; Wetzel, Andreas

In: Palaeogeography, Palaeoclimatology, Palaeoecology, 2013, vol. 376, p. 73–90

Lagoonal carbonates of Kimmeridgian age in NW Switzerland formed in a tropical epeiric sea and exhibit indicators of subaerial emergence such as tidal biolaminites, desiccation cracks, flat pebble conglomerates, and fenestral structures. Additionally, 30 dinosaur tracksites from at least six stratigraphic intervals indicate repeated formation of land bridges between the platform and adjacent...

The paleoecological significance of nerineoid mass accumulations from the Kimmeridgian of the Swiss Jura Mountains

Waite, Richard ; Wetzel, Andreas ; Meyer, Christian A. ; Strasser, André

In: Palaios, 2008, vol. 23, no. 8, p. 548-558

The Kimmeridgian shallow-water carbonates of the Swiss Jura Mountains display stratigraphic levels containing mass accumulations of nerineoidean gastropods. The macro- and microfacies of the rocks with these nerineoidean assemblages suggest that their occurrence was related to water depth, physical energy within the habitat, sedimentation rate, substrate stability, and food supply. Typical...
