Where: Luxembourg, 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 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.
