200 m east of Newlands Farm in the Craighead Inlier (Silurian of the United Kingdom)

Also known as Stratotype locality for Newlands Formation

Where: Scotland, United Kingdom (55.3° N, 4.7° W: paleocoordinates 15.2° S, 23.2° W)

• outcrop-level geographic resolution

When: Demirastrites triangulatus graptolite zone, Newlands Formation, Aeronian (440.8 - 438.5 Ma)

• <3m thick

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; gray, sandy, calcareous siltstone

• The Newlands brachiopod and trilobite faunas are of unusually high diversity for the Lower Silurian and they represent a mixture of genera from both the Stricklandia and Clorinda communities of Ziegler et al. (1968), indicating an ecological position where one assemblage graded into the other. Thus these communities are regarded as having been deposited at the deeper end of the shelf or at its edge.
• a grey sandy siltstone containing a quantity of carbonate material in the interstitial matrix, which weathers to a distinctive ochreish-yellow

Size class: macrofossils

Collected by Cocks & Toghill in 1973; reposited in the BMNH
