Also known as Llano Uplift

Where: Gillespie County, Texas (30.5° N, 99.1° W: paleocoordinates 19.9° S, 91.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Threadgill Member (Tanyard Formation), Gasconadian (485.4 - 477.7 Ma)

• The collection comprises specimens recovered from the Threadgill member of the Tanyard formation for which no further stratigraphic informations (i.e., position within the member) are given. It is possible that these specimens are from the same beds as are those in PBDB collection no. 88805 but there is no indication for it in the primary reference.

• member-level stratigraphic resolution

Environment/lithology: shallow subtidal; lime mudstone

Size class: macrofossils

Preservation: cast, recrystallized, replaced with calcite

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))
