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: coarse channel fill; medium-grained, coarse sandstone and siltstone
•sandstones of site 19 are followed by fragmentary
•plant horizons (Site 20).These are composed of
•plant hash and small wood fragments forming
•thin,1-cm-thick,laminae within medium-to
•coarse-grained massively bedded sandstones,fin-
•ing up to siltstone over 1 m.Rooting is common
•above these hash horizons.These beds are inter-
•preted to represent abandonment and subsequent
•channel fill,with incipient palaeosol formation.
Size class: macrofossils
