Echinoids of the Klinteberg Group on Gotland (Silurian to of Sweden)
Where: Gotland, Sweden (57.5° N, 18.4° E: paleocoordinates 16.5° S, 2.4° W)
• coordinate based on political unit
• local area-level geographic resolution
When: Klinteberg Beds Formation, Homerian to Homerian (426.2 - 421.3 Ma)
• group of beds-level stratigraphic resolution
Environment/lithology: marine; limestone and marl
• Ref. 11073: "In the central ara of Gotland..consists of narrowly spaced reefmounds consisting mainly of tabulates, sstromatopores and bryozoans within a shoal area with coarse and medium-grained biodetritic and crinoidal limestones, which have been extensively transported, washed and sorted. To the west the platform ends with a slope forming the transition to a deeper basin area where limestone-marl alterations were deposited. In the eastern part of Gotland...series of limestones (mainly wackestones and packstones), often oncolitic and with an impoverished fauna. They accumulated in shallow water under back reef to restricted marine conditions."
