• outcrop-level geographic resolution

When: In Beceten Formation, Late/Upper Coniacian to Late/Upper Coniacian (89.3 - 84.9 Ma)

• layer enclosed by two well-dated beds (biostratigraphically), described as "lower Senonian"

•"late Coniacian-Santonian (Báez and Rage 1998)

• bed-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; shale and sandstone

• "fluvial-lacustrine" (Báez and Rage 1998)
• "a formation composed of an alternation of clays and limestones"; vertebrates are in one of the clay beds

•"shales and sandstones" (Báez and Rage 1998)

Size classes: macrofossils, mesofossils

Collected by F. de Broin, D. E. Russell, P. Taquet in 1970-73; reposited in the MNHN

Collection methods: bulk, surface (float), surface (in situ), sieve,

• "Most fossils lie exposed on the ground surface... A large number of the specimens collected came from screen-washing operations" (Báez and Rage 1998)
