TBB2002, Wucaiwan (Jurassic of China)

Also known as Guanlong type site

Where: Xinjiang, China (45.2° N, 88.9° E: paleocoordinates 46.8° N, 91.3° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Upper Member (Shishugou Formation), Oxfordian (163.5 - 157.3 Ma)

• upper part of formation

• bed-level stratigraphic resolution

Environment/lithology: mire or swamp; tabular, bioturbated, tuffaceous, yellow, carbonaceous mudstone

• "from the middle of an approximately 2.0 meter thick tabular bed of finely laminated to massive, tan-coloured, tuffaceous mudstone. Small, horizontal to sub-vertical carbonaceous root traces and plant fragments are present. Fine laminations and horizontally-oriented roots indicate a paludal (wetlands) setting in which sediment accumulated over many years."

Size class: macrofossils
