Abstract

A palynological study of a Llandoverian – lower Wenlockian sequence at Chaleurs Bay (Quebec) has revealed six distinct chitinozoan assemblages whose stratigraphic positions are well known on the basis of brachiopod and conodont data. A comparison of these microfaunas with those described from sequences of the same age in Europe and North America shows that the association Conochitina acuminata, Conochitina flamma, Conochitina cf. C. proboscifera, and Angochitina aff. A. longicollis is the most interesting one. This association is dated as late Llandoverian – early Wenlockian.
