An Anisian Wetterstein limestone reef in North Hungary
In the vicinity of Aggtelek and Josvafo in North Hungary there is a fossil reef formation with an extension of several km2 belonging to the Anisian member of the Wetterstein sedimentary sequence. Surrounded by Dasycladacea-bearing sediments, the reef complex can be split up into three main facies:...

| Tartalmi kivonat: | In the vicinity of Aggtelek and Josvafo in North Hungary there is a fossil reef formation with an extension of several km2 belonging to the Anisian member of the Wetterstein sedimentary sequence. Surrounded by Dasycladacea-bearing sediments, the reef complex can be split up into three main facies: 1. a central reef with colonial corals, hydrozoans and Calcispongia; 2. a reef slope under heavy wave action with a paleobiocoenosis consisting of brachiopods, molluscs and echinoderms; 3. a more quiet-water reef slope with echinoderms and molluscs. The growth of the 500- to 600-m-thick reef complex began in early Pelsonian time and stopped before the deposition of the Upper Illyrian^Diplopora annulatissima Horizon. In the Late Illyrian the entire reef was covered by dasycladaceous sediments. The paper is terminated by the descriptions of a new calcareous sponge (Colospongia catenulata macrocatenulata n. ssp.), a new hydrozoan (Axopora aggtelekensis n. sp.) and a new coral (Protoheterastrea pseudocolumellaris n. sp.). |
