Desertcreat, Pomeroy Inlier (Ordovician of the United Kingdom)

Where: Northern Ireland, United Kingdom (54.6° N, 6.6° W: paleocoordinates 19.1° S, 27.1° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Killey Bridge Formation, Cautleyan (449.2 - 448.8 Ma)

• Was Bardahessiagh (Well Field); However, I think that it really should be Killey Bridge given that most things from Desertcreat are put in the Killey Bridge in later publications.

• member-level stratigraphic resolution

Environment/lithology: coastal; fine-grained, micaceous, gray sandstone

• "The Bardahessaigh Formation was described by Mitchell (1977) as 'grey, fine-grained, micaceous sandstones and rarely corse conglomerates' [...]."

Size class: macrofossils

Preservation: cast

Reposited in the BMNH

• GSM = British Geological Survey
