Also known as Lussant

Where: Poitou-Charentes, France (46.0° N, 0.8° W: paleocoordinates 34.8° N, 1.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Early/Lower Cenomanian (99.6 - 93.5 Ma)

• Subunit B1s is lowermost Cenomanian.

• bed-level stratigraphic resolution

Environment/lithology: paralic; sandstone

• detrital paralic environment

•

•Vullo et al. 2020: beds of the subunit B1 were deposited in shallow marginal marine environments (Néraudeau et al., 2005).

• Vullo et al. 2020: Vertebrate micro- remains (isolated teeth, bones and scales) were intensively collected from a ~0.7-m-thick layer of shelly clayey sand located in the middle part of the subunit B1 (bed B1s) (Néraudeau et al., 2005) (Fig. 1).
