Tchafoue (Jurassic of Switzerland)

Where: Jura, Switzerland (47.4° N, 7.1° E: paleocoordinates 38.4° N, 16.0° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Reuchenette Formation, Kimmeridgian (157.3 - 152.1 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: limestone

• A more regional subdivision of the Reuchenette Formation is based upon lithology (Fig. 2). In ascending stratigraphic order, these are the Bann´e Marls (Gygi, 2000a; Jank et al., 2006), the Nerinean Limestones (Jank et al., 2006; Waite et al., 2008) with dinosaur footprint bearing layers (Marty and Hug, 2003; Marty

•et al., 2007; Marty, 2008), and the Virgula Marls (Jank et al., 2006). Most of the Tropidemys langii specimens were found in the ∼10-m-thick Bann´eMarls, which consist of “grey, decimeterthick layers of marlstones, calcarenitic marls, and marly limestones” (Jank et al., 2006:178). The Bann´e Marls are assigned to

•the Divisum ammonite zone of the Tethyan realm (Jank et al., 2006).

Size class: macrofossils
