The overlaying «Oehningien», an approx. 200 m thick succession of mainly limnic and lacustrine sediments interbedded with numerous paleosols, has yielded many mammal sites (Kälin et al. 2001). A few meters above the base of the «Oehningien» one or two thin bentonite layers have been recorded (FAVRE 1911, Hofmann 1958a, Kälin et al. 2001). At the locality Combe Girard 41, one of these bentonites is associated with a small mammal fauna, indicating an upper MN 6 age (Kälin et al. 2001). The Le Locle Combe Girard bentonite is therefore younger than the Leimbach bentonite of Eastern Switzerland, which is situated in the middle part of MN 6.
