S of Blue Corners, Saratoga Co. ( of the United States)

Also known as Mohawk Valley

Where: Montgomery County, New York (43.0° N, 74.1° W: paleocoordinates 31.8° S, 68.4° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Wolf Hollow Member (Tribes Hill Formation), Skullrockian (487.5 - 482.3 Ma)

• "From the Tribes Hill limestone, from massive beds a few feet below the Hystricurus zone [...]". Given that Hystricurus in the Mohawk valley does occur below and above but not within the Wolf Hollow Mbr. of the Tribes hill (Landing et al., 2003, J. Paleont. 77(1)) and that the Wolf Hollow Mbr. is made up of thromblolite buildups (Landing et al., 2003; Kröger & Landing, 2007, J. Paleont. 81(5)) the locality appears to be within the Wolf Hollow Mbr.

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; limestone

• " [...] the Tribes Hill Formation (Ulrich and Cushing 1910) records predominantly carbonate sedimentation in a shallow shelf setting (Braun and Friedman 1969)." (Westrop & Knox, 1996, Can. J. Earth Sci. 30(8)).

Size class: macrofossils

Preservation: cast

Reposited in the USNM

• RHF = collection of Rousseau H. Flower, transferred to the Smithsonian Institution/U.S. National Museum (see Wolberg, 1990, J. Paleont. 64(3, 5, 6))

Taxonomic list

• In the explanation of pl. 8 figs. 9-11 in Flower (1964) the shell preserved within the living chamber of Caseoceras obesum (misspelled as "Caseoceras obseum") is said to be a Dakeoceras harrisi. However in the text (p. 62) it is explicitly said that the "preservation is such that actually they are unidentifiable specifically".
