Rio Benito (Cretaceous to of Equatorial Guinea)

Where: Equatorial Guinea (1.6° N, 9.6° E: paleocoordinates 12.3° S, 2.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Aptian to Aptian (125.0 - 100.5 Ma)

• Eastman assigned an early Tertiary age ("probably at least as early as the dawn of the Eocene") based his assessment of the fishes, but they are now considered Aptian-Albian.

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine; lithified, black, carbonaceous shale

• "appearances indicate very strongly that they are of lacustrine, or perhaps estuarine origin, certainly not marine"
• Dark-colored fissile shale, containing an abundance of carbonaceous matter, with here and there a few small-sized concretions, valves of Entomostraca, and portions of teleost fish-skeletons, these last being comparatively numerous

Size class: macrofossils

Preservation: adpression
