1. 1. Changes in beyrichiid ostracode faunas during the Late Silurian Lau Event on Gotland, Sweden

   Magister-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Rebecka Rääf; [2010]
   Nyckelord :Gotland; Late Silurian; Lau Event; ostracodes; Beyrichiidae; faunal turnovers; Sensilur; Laukatastrofen; ostrakoder; beyrichiider; faunaförändringar; Earth and Environmental Sciences;

   Sammanfattning : This paper deals with how palaeocope ostracodes of the family Beyrichiidae, from the Silurian strata at Gotland were affected by the Late Silurian Lau Event. The Lau Event is associated with a positive carbon isotope excursion, lithology changes and faunal changes in accumulated strata related to sea-level changes and a glaciation in the Late Ludlow.

   Nyckelord :Lau Event; Late Silurian; Gotland; utdöenden; fjäll; vertebrater; Laukatastrofen; sensilur; early vertebrates; scales; extinctions; Earth and Environmental Sciences;

   Sammanfattning : The Late Silurian Lau Event is one of the three major events identified in the Gotland strata. It is associated with one of the largest stable carbon isotope excursion recorded in the Phanerozoic, as well as rapid lithology changes, and extinctions and faunal turnovers among various fossil groups.
