Geography
Country:France
Coordinates: 44.8° North, 4.8° East (view map)
Paleocoordinates:35.2° North, 14.7° East
Basis of coordinate:based on nearby landmark
Geographic resolution:small collection
Time
Period: Jurassic Epoch: Middle Jurassic
Stage: Callovian 10 m.y. bin: Jurassic 5
Key time interval: Early Callovian
Age range of interval: 165.3 - 161.5 m.y. ago
Stratigraphy
Stratigraphic resolution:group of beds
Lithology and environment
Primary lithology:lenticular,sideritic poorly lithified argillaceous marl
Includes fossils?Y
Lithology description: The lithofacies are schistous marls ravealing former uncemented palesubstrates, with clay very dominating (montmorillonite for 60-70%, calcium carbonates, siderite and limonite for less than 30% or 40%)
Environment:offshore
Geology comments: The water depth is estimated to 200m. The bottom water must have been very quiet and anoxic.
Taphonomy
Modes of preservation:body,cast,soft parts,original chitin,replaced with calcite,replaced with siderite

Reason for describing collection:general faunal/floral analysis
Museum repositories:MNHN
Taxonomic list comments:The gisement contains also some unidentifiable macro algea, some microfossils : foraminifera (Epistomina, Ammodiscus, Trochammina, Ophthalmidium, Dentalina), some polychetes annelids (Ophroditidea and Arenicolodea) and Sipunculidea, some gastropods (caenogastropods), some regular echinoids, some impression and teeth of fish and a cranium of a reptile (Metriorhynchus).
