Also known as Ornithosuchus holotype site
Where: Scotland, United Kingdom (57.7° N, 3.3° W: paleocoordinates 34.0° N, 0.8° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Lossiemouth Sandstone Formation, Carnian to Carnian (237.0 - 208.5 Ma)
• Age of the Lossiemouth Sandstone Formation is based upon vertebrate biostratigraphy, with comparisons made to the faunal assemblages from the lower part of the Maleri Formation (India), the upper part of the Santa Maria Formation (Brazil) and the Ischigualasto Formation (Argentina). This is suggestive of a late Carnian to early Norian age (Benton & Walker 2011).
• group of beds-level stratigraphic resolution
Environment/lithology: dune; lithified, gray, calcareous sandstone
•General description of Lossiemouth Sandstones: "The Lossiemouth Sandstones are white, buff, yellow, or pinkish. Grain size is usually uniform with grains well-rounded. The rock is composed of quartz, feldspar, and rare brownish chert and quartzite. Cements are usually overgrowths of secondary quartz and feldspar, but calcite and fluorspar may also occur. The sandstones may be finely laminated, but more usually they show large-scale cross-beds on well-weathered surfaces. These features, as well as the absence of pebbles, the rarity of micas and heavy minerals, strongly suggest aeolian deposition".
