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: pond; siltstone

• Sedimentary context:between cross-bedded,

•pebbly,coarse-grained crevasse channel sandstone

•units,a siltstone bed occurs with roots and ma-

•ture trees in growth position.The tree tissues are

•poorly preserved.Sediments surrounding the tree

•trunks consist of massively bedded,poorly sorted,

•coarse-grained sandstone overlain by a gravelly

•sandstone at the level of the root flair.This in

•turn is overlain by a horizontally laminated

•well-sorted siltstone with plant remains dominat-

•ed by Araucarites anadyrensis Krysht.shoots and

•branches.
