Fontenoille, Luxembourg (Jurassic of Belgium)

Where: Belgium (49.7° N, 5.0° E: paleocoordinates 37.8° N, 7.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Marnes de Jamoigne Formation, Liasicus (201.3 - 196.5 Ma)

• A. liasicus Zone, Middle Hettangian

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified limestone and lithified marl

• Bed b : 1,5 m Greyish to blue Marls (b1) with thin yellow grey limestone intercalations (b2) at about 1 m from the top

•Bed c : Decimetric limestone lumachelle horizon (c1), with fractures and greyish marl (c2) in the cracks between the blocks. The marly intercalations yielded most of the vertebrate remains described here, with the exception of the larger sharks teeth which were obtained from the lumachelle horizon.
