The Silurian of Gotland consists of m carbonate deposits, spanning the late Llandovery to late Ludlow epochs ( m.y.). Repeatedly, uniform sequences of micritic limestones and marks are interrupted by complex-structured reefs and adjacent platform sediments. The Virtual Silurian Reef is a K distance-learning project of the Geology Section of the Milwaukee Public Museum, funded by the Wisconsin Advanced Telecommunications Foundation. During the Silurian Period in earth history, million years ago, when much of North America was covered by a shallow, tropical sea, reefs flourished in the area now occupied by Wisconsin and Illinois.

Reefs are developed at a number of horizons but are generally little documented in detail. This page is dedicated to ostracods and other microfossils from the Silurian of Gotland.
This Swedish. island preserves an almost complete record of the Silurian Silurian reefs of Gotland book deposits ranging in age from the lower. to upper Silurian (Llandovery to Ludlow). Ostracods are the dominant microfossil but the deposits also.
Mollusca: Gastropods. At least 17 species of gastropods lived as dwellers in the Silurian reefs of Wisconsin. Three of these species, shown above, have been placed in the Silurian reef diorama. One of these species is sometimes found on crinoids (figure 1a) and. Exposed Silurian carbonate deposits with reefs at Hogklint, south of Visby.
Photo: Morten Smelror Around million years ago Gotland comprised a shallow sea lying on the edge of a continent close to the equator. In these warm waters carbonates and fine clastic sediments accumulated among the coral reefs and bioherms.
During the Silurian, the reefs between Saaremaa and Gotland were flourishing to a much larger extent than is visible today. The primary Silurian reef pattern was increasingly destroyed towards.

The Silurian of Gotland, Sweden, consists of m of carbonate deposits. Repeatedly, uniform sequences of micritic limestones and Silurian reefs of Gotland book are interrupted by complex-structured reefs and by adjacent platform sediments. Generally, the alteration of facies is interpreted as the result of sea-level fluctuations caused by a gradual regression with superimposed minor transgressive by: The primary Silurian reef pattern was increasingly destroyed towards Gotland by later erosion.
This has resulted in a large area void of Wenlock reefs off northern Gotland. Off southern Gotland, the narrow conical low-energy deeper-water reefs prevail, as the wave-agitated shallow-water facies with larger and lenticular Wenlock and Ludlow reefs are largely eroded around the Gotland by: 5.

Gotland is built up by a Middle Palaeozoic table-land, with an average height of m, but with some higher hills in the inland and with steep cliffs. Patch reefs up to 35 m thick and generally – m wide, separated by bedded inter-reef sediment, dominate the Högklint Formation (Lower Wenlock) of north-west Gotland.
The spacing between adjacent patch reefs is variable, but is commonly – m. COVID Resources.

Mesophotic Coral Reefs from the Middle Silurian of Gotland, Sweden. The Middle Silurian Period saw a great expansion of reef ecosystems, which spread across a far higher proportion of the seafloor than is the case today, and reached much Author: Joe Bauwens.
Reefs form as 'barriers' in shallower waters and as isolated 'pinnacles' in deeper water. The reefs are formed by a whole collection of different organisms performing different tasks in the reef building process. The principles of the reef building process are the same today as in the Silurian million years ago.

About this book. A newly discovered, diverse sponge fauna of early Silurian age, is described from Gotland, Sweden. This is the first Silurian sponge assemblage known from Baltica, and the only diverse Llandoverian assemblage known worldwide.
The fauna includes 20 genera and 29 species, of which three genera and six species are new. Gotland, a Silurian-aged coral-reef island with white sand beaches, lies not in the tropics but in the Baltic Sea off the southeastern coast of Sweden just a short trip from Stockholm. In addition to the carbonate geology, visitors can view medieval churches and thatched-roof Viking farms, and experience the moody, atmospheric weather featured in the films of director Ingmar Bergman.
53 Chapter V THE FOSSIL REEFS OF GOTLAND, GENERAL Now that a general view has been obtained of the picture in which the Silurian reefs of Gotland fit, we may in this chapter begin a more detailed description of these reefs by discussing their typological, geographical and stratigraphical distribution and organic and lithological composition.
Silurian stromatoporoid-dominated reefs of Gotland, Sweden, are bioherms and biostromes formed during phases of reduced clastic supply.
Well-exposed examples are in the early Wenlock Högklint Formation and middle Ludlow Hemse Group. Reef development culminated in shallow water biostromes, laterally expanded over a stabilized substrate and associated with frequent erosion Cited by: Title.

The reef belongs to the Sundre formation, and overlies the Hamra. Gotland is made up of a sequence of sedimentary rocks of a Silurian age, dipping to the south-east. Reef constructors help to build the reef by forming a framework of hard skeletons. Silurian reefs of million years ago share many features in common with those of today, including tropical to subtropical distribution, growth in shallow water, and relatively high biodiversity.
