Wierzbica, track layer (Jurassic of Poland)

Where: Wojewodztwo mazowieckie, Poland (51.3° N, 21.1° E: paleocoordinates 43.1° N, 27.5° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Wierzbica Oolite and Platy Limestones Formation, Early/Lower Kimmeridgian (155.7 - 150.8 Ma)

• bed-level stratigraphic resolution

Environment/lithology: peritidal; gray marl and graded, glauconitic, shelly/skeletal, muddy grainstone

• "upper tidal flat". Tracks were subsequently buried by a tidal channel.
• Pterosaur footprints at top of a "20 cm thick, laterally discontinuous grey/brownish laminated marl layer", and preserved as casts on the bottom of a "layer of organodetritic marls with shell debris, quartz grains, carbonate rock fragments, glauconite and floral debris...The term 'marl' can be assigned only to the uppermost part of the layer, while for the most part, particularly in the lower section of the layer, this rock should be assigned to grainstone"

Size class: macrofossils

Preservation: cast, trace

Collected by Roniewicz in 2004
