Abstract
Arrow-shaped P1 elements of Dollymae are characteristic for the Tournaisian conodont faunas worldwide but the phylogeny of this conodont remains obscure and its origin is cryptic. Dollymae peregrina n. sp., from the upper Famennian (upper expansa Zone) strata in the Holy Cross Mountains (central Poland), is the oldest representative of the Dollymae lineage. The morphology of the new species’ P1 element shows primitive features in comparison to other members of this genus and is transitional in the number of element processes. Thus D. peregrina n. sp. is most probably ancestral to the remaining species. The genus appears to be monophyletic, probably rooted in Pelekysgnathus within the Icriodontidae.
