| Summary: | The purpose of this paper is to propose a chitinozoan zonation of the Ordovician of Quebec and western Newfoundland. On the basis of chitinozoan assemblages previously described from various sections, covering almost the entire Ordovician System, 22 biozones, based on first appearance of index species, are distinguished. As the strata from which the chitinozoan microfaunas were extracted are well dated by other fossils, especially graptolites, it is possible to establish a correlation between the chitinozoan and the established graptolite and conodont zonations of North America and Great Britain. |
