Formation:Ardnish Member:Hallaig Sandstone
Lithology and environment
Primary lithology: "shale"
Includes fossils?Y
Lithology description: Here the Ardnish Formation predominantly comprises micaceous shales and siltstones with clean, medium- to fine-grained sandstones exhibiting bipolar tabular and trough cross-beds (e.g. the Hallaig Sandstone Member of Hesselbo et al. 1998). These cross-bedded units, which contain abundant marine fossils at the bases of coarsening-up cycles, are interpreted as representing deposition in a shallow-marine/ estuarine environment with a tidal influence (Hesselbo & Coe 2000).

Collection method comments: SM 1976.1999.8 was found loose on the shore at Boreraig (Suisnish, south Skye) by one of the authors (C.C.J.M.) in 1997 (MacFadyen 1997) (Fig. 1). It was later collected by another of the authors (D.A.R.) and Martin Wildgoose in 1999. NMS G. 2014.21.1 was found during a 2013
