• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Assise des Carreaux Formation, Late/Upper Callovian (164.7 - 161.2 Ma)

• The Assise des Carreaux Formation is dated to the upper Callovian by abundant ammonites: the basal beds yielded species Peltoceras cf. baylei Prieser, 1937, Hecticoceras rursicostatum (Buckman, 1924) characteristic of the Athleta biozone, while the upper beds yielded species Kosmoceras dunkani (Sowerby, 1817), Quenstedtoceras lamberti (Sowerby, 1819) characteristic of the Lamberti biozone.
