• coordinate estimated from map
• outcrop-level geographic resolution
When: Krivorechenskaya Formation, Albian to Albian (113.0 - 93.9 Ma)
• uppermost Albian to Lower Cenomanian
• group of beds-level stratigraphic resolution
Environment/lithology: pond; siltstone
•pebbly,coarse-grained crevasse channel sandstone
•units,a siltstone bed occurs with roots and ma-
