Wozniki clay pit (upper layer) (Triassic of Poland)

Where: Slaskie, Poland (50.6° N, 19.0° E: paleocoordinates 25.8° N, 20.4° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Carnian (237.0 - 228.0 Ma)

• Age of the strata at Wozniki is constrained by dates assigned to the underlying and overlying lithostratigraphic units and biostratigraphic data (conchostracans). Overlying strata are lithostratigraphically correlated to units of mid-late Norian age. Spinicaudatan specimens from a greenish-grey claystone (about 20 cm thick), located about 20–30 cm below the horizon yielding bones, include Laxitextella cf. laxitexta and another, unidentified, species of the same genus, which suggests that the age of the stratum lies within the mid–late Carnian (Sulej et al. 2011)

• bed-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; gray mudstone

• gray mudstone layer

Size classes: macrofossils, mesofossils

Collected by Sulej in 2007

Collection methods: quarrying, surface (in situ), mechanical,
