Where: Sweden (56.8° N, 12.6° E: paleocoordinates 46.0° N, 11.4° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Late/Upper Cenomanian (99.6 - 93.5 Ma)
• reworked phosphatised rock fragments found in the limestone and the sandstone (Särdal beds); 'based on the presence of Actinocamax ex gr. primus/plenus, can be assigned to the late Cenomanian and/or the A. plenus Zone between the Cenomanian and the Turonian. it is also possible that the Turonian and/or Coniacian may be represented by some rock pieces, but this cannot be verified at present'
• group of beds-level stratigraphic resolution
Environment/lithology: open shallow subtidal; lithified, fine-grained, gray grainstone
Size classes: macrofossils, microfossils
Collection methods: authors and amateur collections;
•Museum repositories: Geological Survey of Sweden (EN), the Mineralogical Museum in Copenhagen (MMH), Geological Institute in Lund (LO)
