Brusturi Mine, Cornet 204 lens (Cretaceous of Romania)

Also known as Bihor, ETE 1554

Where: Judetul Bihor, Romania (47.0° N, 22.4° E: paleocoordinates 28.1° N, 27.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Lower Bauxite Formation, Berriasian (145.0 - 139.8 Ma)

• bed-level stratigraphic resolution

Environment/lithology: karst; lenticular, brown, red, silty conglomerate and red, yellow claystone

• "an extensive karst surface, formed after uplift of the unlderlying limestones, providing clear evidence of subaerial erosion and tropical conditions of soil development. The bauxite occupied karst depressions to a depth of several metres, often filling caves and fissures."
• "[lens is] 3 m of red-brown boehmitic bauxite, consisting of alternating 300 mm thick beds of structureless mud-grade bauxite and 40-100 mm thick arenitic or arenitic/ruditic units...the bauxite is capped by 0.5 m of laminated kaolinitic clay of mottled yellow and red colour, and this is topped...by limestone. The bones occurred in greatest concentration in a 0.6 m thick band in the middle of the lens...virtually a bone-supported conglomerate...the bones were found in the mud-grade bauxites in the lower 1 m of the section."

Size classes: macrofossils, mesofossils

Collected by F. Marinescu in 1978-1979, 1994-2000

Collection methods: bulk, salvage, chemical, mechanical,

• 2000 bone-bearing blocks collected (size unspecified); discovered by two ore miners. Collected 1978-1979 by F. Marinescu; mine flooded 1984-1994; reopened 1994-2000 when studied by Tarii Crisurilor Museum and Univ. Bristol; re-flooded 2000.
