Wenxiyuan tracksite (Cretaceous of China)

Also known as Jimo

Where: Shandong, China (36.4° N, 120.4° E: paleocoordinates 39.3° N, 123.1° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Qugezhuang Formation (Laiyang Group), Early/Lower Aptian (125.5 - 122.5 Ma)

• 2-3 closely spaced layers

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial; fine-grained, medium, green, yellow sandstone

• "Anastomosing river paleoenvironment"
• "yellow-green, medium-fine sandstone (Fig. 2). No desiccation cracks or ripple marks were observed..."

Size class: macrofossils

Preservation: mold/impression, trace

Collected by Y.-G. Yang in 2011

Collection methods: salvage, surface (in situ),

• LUGP: Institute of Geology and Palaeontology, Linyi University

•Tracks were discovered during construction in April 2009 5 metres below the surface but were mostly not collected, and were covered by buildings. Later, in May 2011, pterosaur tracks were collected on a single slab from a neighbouring building site.
