Where: Bourgogne, France (47.3° N, 5.0° E: paleocoordinates 37.8° N, 14.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Early/Lower Callovian (164.7 - 161.2 Ma)

• Macrocephalus zone.

•"The stratigraphic position of the sample is very exactly known since it comes from the top of the few meters of limestones superimposed on the marls with Brachiopodes."

• Dominated by bioclasitic "calcaires" and oolites in flagstones with oblique stratifications.

Size classes: macrofossils, microfossils

Collection methods: salvage,

• Vertebrate specimens were in a block of "calcaire".

•Collection of the l'Institut des Sciences de la Terre de l'Université de Dijon.
