Tramore Bay, near Newton (Ordovician to of Ireland)

Where: Munster, Ireland (52.2° N, 7.2° W: paleocoordinates 57.2° S, 23.1° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Tramore Limestone Formation (Duncannon Group), Llandeilo to Llandeilo (466.0 - 457.5 Ma)

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; nodular, shelly/skeletal, gray, blue, argillaceous limestone and calcareous siliciclastic

• "The Formation consists of grey calcareous mudstones, siltstones, and sandstones with interbedded blue-gray argillaceous nodular limestone beds containing a rich shelly fauna [...]" Wyse Jackson (2002, in Wyse Jackson et al.(eds.): Bryozoan Studies 2001, and references therein). It is not stated by Evans (2002) but the cephalopod fossils very likely are from the nodular limestones.
