Foreshore near Flodigarry (Jurassic of the United Kingdom)

Where: Scotland, United Kingdom (57.7° N, 6.2° W: paleocoordinates 47.6° N, 4.3° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Belemnite Sands Member (Staffin Bay Formation), Early/Lower Callovian (164.7 - 161.2 Ma)

• The boulder was found close to locality 3, excursion 21 of Bell and Harris (1986) where the succession youngs to the west. The Staffin Bay Formation is well exposed at this locality allowing much detail of the section to be recorded

•A comparison between the faunal content (the abundance of bivalves and belemnites) and sedimentological characteristics of the boulder, suggests that it may correlate lithologically within the Belemnite Sands (Lower Callovian) of the Staffin Bay Formation (Hudson and Morton 1969)

• member-level stratigraphic resolution

Environment/lithology: marine; burrowed, medium-grained, coarse, calcareous sandstone

• The boulder consisted of a 60 cm-thick medium to coarse-grained sandstone containing vertical burrows and plant material with a thin plant-rich horizon 20 cm from the top.

•The entire boulder was cemented by calcite which has retarded erosion and protected the bones against extensive damage

Size class: macrofossils

Collected by F. Nimmo in 2nd July 1992

Collection methods: surface (float), acetic,

• Specimens have been deposited in the Hunterian Museum, Glasgow University (GLAHM).

•The boulder was carefully split and transported to be reassembled in the Hunterian Museum. The fragments were soaked overnight in dilute domestic bleach to remove barnacles and limpets. The vertebra and neural spine were further prepared by etching with 10% acetic acid to remove the surrounding carbonate cemented sand. The bones were highly fractured due to compaction and care had to be taken to recover and reposition the fragments using a water based adhesive. The
