Strud, Namur Province (Devonian of Belgium)

Where: Belgium (50.4° N, 5.1° E: paleocoordinates 17.3° S, 4.5° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Palmatolepis expansa conodont zone, Crupet Member (Evieux Formation), Late/Upper Famennian (364.7 - 360.7 Ma)

• PJW: Was Bois-des-Mouches; however, Denayer et al. (2016: Geol. Magazine) note that: 1) Bois-des-Mouches is a synonym of both the Montfort and Evieux formations (which are one after the other), and, 2) this is the Crupet member of the Evieux. The is in the expansa conodont zone, and thus Late Fammenian. Evieux overlies Montfort and underlies either Comblain-au-Pont (Dinantian Syncline) or Dolhain (Vesdre area). Crupet overlies the Royseux member & underlies the Comblain-au-Pont or Dolhain.

• bed-level stratigraphic resolution

Environment/lithology: pond; lithified, gray siltstone

• It was found in a freshwater association including plants, numerous Crustacea (Branchiopoda and Malacostraca) and Chelicerata (Eurypterida). Corresponds to one of the last channel-filling phases and is topping a 1.4 m-thick fining-upward point-bar deposit. It yielded a diverse association transported from various part of the floodplain or even from upstream environments. This layer is covered by slowly accumulated floodplain green to black shales and siltstones becoming red up-section. They witness of seasonally dried and flooded freshwater ponds.
• Dark gray siltstone.
