Iharkút mine, Bakony mountains (Cretaceous of Hungary)

Also known as Németbánya

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 (85.8 - 84.9 Ma)

• two bone-bearing beds within section, approx. 0.5 m apart

• group of beds-level stratigraphic resolution

Environment/lithology: fine channel fill; sandy claystone and gray, argillaceous sandstone

• "deposited in an alluvial plain"; fossils "are buried in mud- and sand-filled channel deposits"

•"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).

• "The Csehbánya Formation consists of variegated clay and sandstone beds...The fauna is concentrated near the top of the outcrop in 20 cm thick sandy clay, sandstone bed...Most of the fossils derived from 5 cm thick sandy clay layer below the sandstone. Other teeth and bones occur disordered on the surface of the sandstone bed and are covered with clay less than 1 cm thick."

•"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)
