Where: Ireland (53.5° N, 9.4° W: paleocoordinates 18.5° S, 24.1° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kilbride Formation, Telychian (438.5 - 433.4 Ma)

• STRATIGRAPHIC RELATIONS: From the Kilbride Fm, which overlies the Lough Mask Fm, and is overlain by the Tonalee Fm. AGE: Late Llandovery on the basis of conodont biostratigraphy. STRATIGRAPHIC POSITION: From the Annelid Grits, in the lower part of the Kilbride Fm.

•Telychian according to Evans (1994. Irish J. Earth Science 13:113-148.

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified, coarse-grained, shelly/skeletal, calcareous sandstone

Size class: macrofossils

Preservation: original calcite, original phosphate

Collection methods: bulk, chemical, hydroflouric, sieve,

• COLLECTOR: Aldridge et al. REPOSITORY: James Mitchell Museum, University College, Galway. METHODOLOGY: Two samples, one of 5 kg and one of 0.55 kg, were processed and the residues concentrated using bromoform. To attain complete breakdown, the smaller sample was also treated with hydrofluoric acid.
