Pulali Point, Aldwell Formation (Eocene of the United States)

Where: Jefferson County, Washington (47.7° N, 122.9° W: paleocoordinates 49.4° N, 107.8° W)

• coordinate estimated from map

When: Aldwell Formation, Middle Eocene (48.6 - 37.2 Ma)

• Narizian

Environment/lithology: marine; conglomerate and sandy siltstone

• boulder conglomerate, sandy siltstone, and siltstone with gradational contacts between each (Squires et al., 1992). The boulder conglomerate, located at the base of the section, contains crab fossils in siltstone concretions occurring with a pre- dominance of basalt boulders (Squires et al., 1992). The concretions were considered by Squires et al. (1992) to have been reworked. Decapods were also recovered from the silty sandstone facies and were contained within reworked, well-indurated siltstone concretions (Squires et al., 1992)

Size class: macrofossils
