Where: Gotland, Sweden (57.7° N, 18.5° E: paleocoordinates 21.4° S, 2.9° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Kockelella walliseri conodont zone, Conchidium tenuistriatum Member (Slite Formation), Sheinwoodian (433.4 - 430.5 Ma)
• Slite C in Lindström; given area and lithology, this should be in the Conchidium tenuistriatum beds of the Slite.
•This is the middle Kockelella walliseri zone.
• group of beds-level stratigraphic resolution
Environment/lithology: lithified limestone
•From Samtleben et al. (1996). Geol. Rundsch 85:278-292; "...this unit consists of a carbonate platform with reef mounds and surrounding shoal sediments of mostly pure biodetritic and pleoidal limestones. Here slow and discontinuous accumulation of carbonate material continued in a very shallow water but under normal marine conditions....to the south and southwest the carbonate platform passes with a conspicuous slope into a deeper shelf basin where a uniform alternation of micritic limestones and marls accumulated."
