Where: Hunedoara, Romania (45.6° N, 22.9° E: paleocoordinates 32.7° N, 21.1° E)
• coordinate based on nearby landmark
When: Sânpetru Formation, Maastrichtian (70.6 - 65.5 Ma)
• "yielding a profile with progressively younger deposits and with a vertical thickness reaching approximately 2 km"
• formation-level stratigraphic resolution
Environment/lithology: "floodplain"; paleosol/pedogenic sandstone and gray, green, red mudstone
• "Floodplain sedimentation is represented by paleosols"
• "At location 6, in addition to the channel facies, sheets of parallel-bedded sandstones up to 1 m thick are observed. The bottoms of the sand bodies show little erosion and are laterally associated with channel deposits. Floodplain sedimentation is represented by paleosols, for which the following horizons may be distinguished: a red horizon with parallel lamination and a level with moderate to well-developed concretions (up to 10 cm) underlined by parallel stratified mudstones with the color changing progressively from red to mottled textures involving grey-green and red drab-haloes. Paleosols from this outcrop are dominated by calcisols, and vertisols without a calcic horizon are found only sporadically. Smectite is the most frequent clay mineral, 55 to 68 mass %; subordinate chlorite and illite are also present."
