Angelokastro village, probably Potami Fm, sample GR 62B (Jurassic of Greece)

Where: Greece (37.7° N, 23.0° E: paleocoordinates 20.5° N, 20.9° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Potami Formation, Pliensbachian (190.8 - 182.7 Ma)

• Late early to late Pliensbachian

Environment/lithology: deep subtidal; cherty/siliceous shale

• Dark reddish-brown, radiolarian-bearing cherty shales with disrupted fragments

•of chert, occurring in the footwall of a thrust bringing them into contact with Pantokrator Limestone.

•It may be part of the sediments of the Migdhalitsa Ophiolite Unit (see Capedri

•et al. 1996) or may be a large (olistolithic) block in the Potami Formation of the Basal Sequence of the Dhidhimi–Trapezona Composite Unit.

• Ferromanganese nodule with chert core.

Size classes: mesofossils, microfossils
