Yelisseev-24 (Cretaceous to of Russian Federation)

Also known as Yelisseev locality, Grebenka flora

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

• Sedimentary context:this site is situated later-

•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
