Fintina lui Mitilan (upper faunal level), Tetoiu 2 middle faunal horizon (Pleistocene of Romania)

Where: Romania (44.7° N, 23.9° E: paleocoordinates 44.7° N, 23.8° E)

• coordinate based on nearby landmark

When: Early/Lower Pleistocene (2.6 - 0.8 Ma)

• Early Pleistocene. Faunal comparison indicates that the Middle Faunal Horizon (Tetoiu 2) correlates with the ?Tasso faunal unit, Seneze zone, Eburonian cold stage and Domashkinianhorizon/Odessan faunal complex. The middle faunal horizon corresponds to a general cooling and drying of the climate. The deposits consist of a basal succession of clays and sands, 8m thick, which underlies a sequence 6m thick, consisting predominantly of sands with gravel lenses. The upper faunal level consists of sands and gravels 0.5m thick, 0.7-1.0m above the main (lower) faunal level.

Environment/lithology: fluvial-lacustrine

• The Middle faunal horizon is at the top of a 40m sequence of sands with gravel and pebble lenses and thin clay intercalations. 'The beds have an average dip of 1 to 2 degrees SE.' 'Two metres above the upper faunal level, frost structures (ice wedges, involution pockets) were recorded.'
• Sands and gravels.
