• coordinate based on political unit

When: VCo spore Biozone zone, Evieux Formation, Late/Upper Famennian (364.7 - 360.7 Ma)

• Found on the northern rim of the Dinant Synclinorium

Environment/lithology: estuary or bay; gray mudstone

• an estuary channel of which the axis (N-S), is perpendicular to the outcrop surface.

•Fairon-Demaret (2001, p.81): The channel fill includes a clay plug indicative of a switch from tide influenced estuary deposits with lateral arenaceous accretion structures to alluvio-fluvial deposits of horizontal gray to dark mudstone beds.

• This assemblage occurs in grey to dark mudstones
