Palaeogeographical patterns in Late Ordovician bryozoan morphology as proxies for temperature

Popis výsledku v původním jazyce

Several studies have revealed temperature-related patterns in the morphological characters of the colonies of recent bryozoans, but comparable studies on Paleozoic bryozoans are lacking. In this paper a statistical analysis of the morphological differences is undertaken between congeneric eurythermic cosmopolitan species of 10 Upper Ordovician bryozoan genera from warm- and cold-water settings from the Mediterranean, Avalonia, Baltic and Laurentia-Siberian provinces. The study involved the measurement of 28 morphological characters in 156 samples belonging to 104 different species. The univariate statistical analysis showed that there are clear morphological differences between cold- and warm-water species in six of the ten Late Ordovician bryozoan genera analyzed in this study, while the discriminant analysis was able to classify correctly at the 95% confidence level as warm- or cold-water the species of four of the ten studied genera.
