Etrochey Callovian vertebrate layer (Côte-d'Or) (Jurassic of France)

Also known as Bourgogne, Burgandy, Cote-d'Or

Where: Bourgogne, France (47.9° N, 4.6° E: paleocoordinates 38.3° N, 14.2° E)

• coordinate based on political unit

• outcrop-level geographic resolution

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

• "The bones of Steneosaurus sp. were collected in the "Carrière de Grande Roche" in the South [sic? should be north based on the map] of the village comes from the same limestone deposits as the flora of Etrochey, above limestones of Etrochey themselves with Burmirhynchia and oncoides often strongly dolomitized and rust-stained."

•"They are two meters white bioclastic and oolitic limestones with

•micritic cement, which show an oblique plane of stratification: the bones

•and other fossils are in the same massive bench and dissociated; the

•branches of plants are plated on the surface of the benches."

•translated by RW

• bed-level stratigraphic resolution

Environment/lithology: ooidal, white limestone

• possibly a small island temporarily emergent on the Callovian carbonate platform
• white bioclastic and oolitic limestones with

•micritic cement, which show an oblique plane of stratification

Size class: macrofossils

Preservation: replaced with dolomite

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