Valea Roscai, Tetoiu 1 lower faunal horizon (Pliocene of Romania)

Where: Romania (44.8° N, 23.9° E: paleocoordinates 44.9° N, 23.6° E)

• coordinate based on nearby landmark

When: Pliocene (5.3 - 2.6 Ma)

• Late Pliocene, just before the Olduvai event (based on palaeomagnetism). Faunal comparison indicates that the Lower Faunal Horizon (Tetoiu 1) correlates with the upper part of the Khaprov faunal complex, upper MN17 (St Vallier Zone), probably equivalent to the Tiglian warm stage.

•Site is about 98m below the top of the section, and consists of a succession of sands 1m thick, fossil remains come from the base of these sands.

Environment/lithology: fluvial-lacustrinesandy

• The lower faunal horizon is in an approximately 20m thick bed consisting 'predominantly of silty sands and sand, levels with gravels and larger pebbles were also observed. These beds are rich in faunal remains.'

•'The beds have an average dip of 1 to 2 degrees SE.'

• A succession of sands 1m thick, fossil remains come from the base of these sands.
