Lynslie Burn, Pentland Hills, SW Edinburgh (Silurian of the United Kingdom)

Also known as Eoplectodonta penkillensis Assoc., low Wether Law Linn Fm., Pentland Hills

Where: Scotland, United Kingdom (55.8° N, 3.4° W: paleocoordinates 15.9° S, 20.8° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Cyrtograptus lapworthi graptolite zone, Grain Heads Siltstone Member (Wether Law Linn Formation), Telychian (438.5 - 433.4 Ma)

• Was just Lower Member.

• member-level stratigraphic resolution

Environment/lithology: marine; bioturbated, sandy siltstone

• Judged to consist of disturbed neighborhood assemblages. Fossils rarely damaged, locally in life position. May be biocoenosis. Remains not concentrated, suggesting rapid sedimentation. Moderately high energy environment. Free lying, low-level suspension feeders are typical. Vagile epifauna,scarce infauna. Remains disturbed slightly after death, mainly by currents.

•Overall sequence of sediments treated here "represents a marine regression from offshore turbidite facies, through shallow water facies with abundant flora and fauna, to terrestrial red beds, of Old Red Sandstone facies. Sediments belonging to the highest Cock Rig Formation and Lower Member of the Wether Law LInn Formation constitute part of the shallow water marine facies."

• found in laminated fine-sandy siltstones. These are relatively poorly bioturbated.

Size class: macrofossils

Collection methods: Author gives percent abundance data, averaged over numerous sampled blocks.
