Also known as Németbánya, Iharkut, SZ-6
Where: Veszprém, Hungary (47.2° N, 17.6° E: paleocoordinates 31.0° N, 18.6° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Csehbánya Formation, Santonian (86.3 - 83.6 Ma)
• two bone-bearing beds within section, approx. 0.5 m apart
• group of beds-level stratigraphic resolution
Environment/lithology: crevasse splay; green, sandy claystone and pebbly, gray, green, argillaceous sandstone
•"The palaeoenvironment is interpreted as an alluvial plain and the deposition of the breccia could be the result of the episodic filling of a channel or pond by debris flows, silt and sand" (Osi & Mindszenty, 2009).
•"a flash-flood sequence deposition, which started with a high flow regime characterized by sandstone and clay clasts, whereas the siltstone layers are indicative of waning flow velocity and deposition from suspension in standing water, following the minor flow pulse. Along with its taphonomic characteristics, this sedimentology suggests that Unit 1 was deposited by ephemeral high-density flash-flood events probably triggered by episodic heavy rainfalls." (Prondvai et al. 2017)
•"The vertebrate-bearing beds form 2–3 m thick cyclical units beginning with green clay covered by breccia containing clay clasts, sandstone and siltstone layers (Tuba et al. 2006). Most of the material, including the turtles comes from the matrix supported breccia consisting of ripped-up variegated clay clasts, dolomite pebbles, carbonized plant remains and sand forming channel-like structures with the isolated bones accumulated in lenses" (Rabi et al. 2012)
•SZ-6: "a 10–50-cm-thick basal breccia layer composed of gray-green sand, siltstone, clay clasts, and pebbles. The poorly sorted sandy breccia is interrupted by laminated siltstone horizons; these coarse- and fine-grained layers are repeated several times resulting in a stacked fining-upward series of units."
