Houzuoshan Dinosaur Park (Cretaceous to of China)

Also known as Junan

Where: Shandong, China (35.2° N, 118.7° E: paleocoordinates 39.0° N, 118.8° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Tianjialou Formation (Dasheng Group), Barremian to Barremian (129.4 - 100.5 Ma)

• 12 different levels within formation at this site

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine; medium-grained sandstone and red, blue, argillaceous siltstone

• "Light grey purple medium-grained feldspar sandstone, interbedded with dark purple muddy siltstone to form rhythms. Medium-grained feldspar sandstone usually 0.5?2 m thick, with well developed cross bedding; muddy siltstone bed generally 10?30 cm in thickness, with well developed sedimentary structures such as mudcracks, ripple marks and even ice crystal marks. Fossil bird tracks, in association with abundant dinosaur tracks were discovered from this bed."

Size class: macrofossils

Preservation: mold/impression, trace
