Where: Tunisia (36.8° N, 9.6° E: paleocoordinates 22.6° N, 14.3° E)
• coordinate estimated from map
When: Crioceratites loryi ammonoid zone, H1 Member (El Mergueb Formation), Early/Lower Hauterivian (136.4 - 130.0 Ma)
• The section JBH-B starts after a lateral displacement of 10m to north–west from the top of section JBH-A. About 20m of limestone–marl alternations of the upper Valanginian are exposed at the base of the succession. The Hauterivian is represented by 783m of thickness, including a 65m gap of observation.
Environment/lithology: marine; lithified, calcareous limestone
Size class: macrofossils
Preservation: cast, mold/impression, original aragonite, original calcite
