Evolution and Motility of Blastozoan Echinoderm Stalks in the Ordovician of the Baltic Paleobasin

Key Points

This research examines the evolution and motility of blastozoan echinoderms in the Ordovician period.
Analyzed heteromorphic stems of three Glyptocystitoida genera from the Middle Ordovician of the Leningrad Region.
Compared motility data with that of Laurentian Pleurocystitidae.
Studied fossil evidence from the Baltic Paleobasin.
Identified differences in stem morphology and potential motility among the analyzed genera.
Provided insights into the evolutionary adaptations of echinoderms during the Ordovician period.
Found comparative aspects of motility between blastozoan and crinozoan echinoderms.

Abstract

Blastozoan and crinozoan echinoderms are studied from the Ordovician of the Baltic Paleobasin providing evidence for comparative aspects of their evolution. The study particularly focused on heteromorphic stems of three genera of the superfamily Glyptocystitoida from the Middle Ordovician of the Leningrad Region, examining their possible motility in comparison with stem motility data on Laurentian Pleurocystitidae.
