Also known as Cromhall Quarry, Slickstones
Where: England, United Kingdom (51.6° N, 2.4° W: paleocoordinates 36.5° N, 0.9° E)
• coordinate stated in text
• small collection-level geographic resolution
When: Rhaetian (205.6 - 201.6 Ma)
• Whiteside & Marshall (2008) argue for a Rhaetian age based upon the shared presence of Planocephalosaurus with deposits at Tytherington dated as Rhaetian on the basis of palynomorphs, and the presence of fish remains that are typical of the Rhaetian Penarth Group.
• group of beds-level stratigraphic resolution
Environment/lithology: fissure fill; lithified limestone and green mudstone
Size classes: macrofossils, mesofossils
Collection methods: bulk, chemical, mechanical, acetic,
• Material in University of Aberdeen palaeontological collection
•Bone material is extracted from well cemented sediments by placing them in acetic or formic acid baths (between 5 percent and 15 percent solution) and then thoroughly washing and sifting the residues. However, where the bone occurs in soft marls it must be removed manually using fine needles.
