Brachiopod faunal dynamics during the Silurian Ireviken Event, Gotland, Sweden
Populärvetenskaplig sammanfattning: Brachiopodernas öde under Irevikenkatastrofen. För ungefär 430 miljoner år sedan, under tidsperioden silur, låg det område som idag är Gotland under havsytan i ett varmt, grunt hav strax söder om ekvatorn. Stora mängder kalk och lera avlagrades på havsbottnen och i havet levde bl.a. cephalopoder, trilobiter, fiskar och brachiopoder (armfotingar), det senare en bThe brachiopod fauna from parts of the Lower and Upper Visby formations on Gotland has been investigated through a combined outcrop and literature study. The strata of these formations were formed during the Ireviken Event, one of the severest identified oceanic events on Gotland, with diversity changes and extinctions among several groups of marine taxa. Seven bulk samples were collected from str
