Shennvfeng tracksites (I, II, III, IV, V) (Cretaceous to of China)

Also known as Hami, Pterosaur-Yadan National Geological Park, Goddess Peak

Where: Xinjiang, China (42.7° N, 92.6° E: paleocoordinates 41.6° N, 95.7° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Tugulu Group, Barremian to Barremian (129.4 - 113.0 Ma)

• unclear whether it is in the mapped Taizicun Formation (Paleocene), which therefore also includes Cretaceous, or belongs to an unmapped formation below it.

• bed-level stratigraphic resolution

Environment/lithology: fluvial; medium-grained sandstone and tabular, fine-grained sandstone

• "The sedimentary facies in the study area consist of medium-thick bedded poorly sorted, coarse to very coarse, cross bedded fluvial sandstones with local pebble-filled channels. The coarser sandstones and conglomerates contain angular rip up clasts of finer sandstone, large disarticulated dinosaur bone fragments and fossil wood (Figs. 2–4). There are local water escape structures, and rare root casts. Locally one may observe tabular flat topped units of fine sand, some of which have been trampled or “dinoturbated” (sensu Lockley, 1991) by large trackmakers."

Size class: macrofossils

Preservation: cast, mold/impression, trace
