Quarrington quarry (Permian of the United Kingdom)

Where: England, United Kingdom (54.7° N, 1.5° W: paleocoordinates 17.3° N, 14.6° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Marl Slate Formation (Zechstein Group), Wuchiapingian (259.9 - 254.2 Ma)

• the Marl Slate is the "first member of the English Zechstein succession" (Pettigrew, 1979) and equivalent to the Kupferschiefer of Germany. Brauns et al. (2003) reported a date of 257.3 +/- 2.6 Ma (Wuchiapingian) for the Kupferschiefer based on a Re-Os geochronological study. The presence of the conodont Mesogondolella britannica in Kupferschiefer equivalents supports a middle Wuchiapingian age.

•According to the British Geological Survey Lexicon of Named Rock Units (http://www.bgs.ac.uk/lexicon/lexicon.cfm?pub=MLSL) the Marl Slate has formational status and is a subunit of the Zechstein Group.

• bed-level stratigraphic resolution

Environment/lithology: coastal; yellow claystone

• Near-shore environment, with deposition in a sea of normal salinity and a depth of up to 60 metres

Size class: macrofossils
