Where: Russian Federation (64.5° N, 168.9° E: paleocoordinates 78.6° N, 166.0° W)
• 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: crevasse splay; siltstone and carbonaceous shale
•ally 12 m along a section to the south of site 23
•and about 1 m above stratigraphically (Fig.5).
•Here,a horizontally bedded siltstone occurs,
•with abundant organi material grading up into
•a thinly laminated carbonaceous paper shale.The
•development of the organic-rich horizon is termi-
•nated abruptly by pebbly crevasse channel sand-
•stone deposits.
Size class: macrofossils
