An Early Ordovician Trilobite assemblage from the Lashkarak Formation, Damghan area, northern Iran Assemblage à trilobites de la Formation de Lashkarak, Ordovicien inférieur de la région de Damghan, Nord de l'Iran

Résumé

A low diversity Lower Ordovician trilobite assemblage is described from the middle part of the Lashkarak Formation at Simeh-Kuh, northwest of Damghan, northern Iran. Co-occurrence with conodonts of the lowermost Paroistodus proteus Biozone suggests an uppermost Tremadocian age. This assemblage includes four taxa, including one new genus and two new species, Damghanampyx ginteri nov. gen. nov. sp. and Asaphellus fecundus nov. sp. The third diagnosable species from the formation is Taihungshania miqueli (Bergeron, 1894) which has previously been reported from southern France and the Turkish Taurides, suggesting north Gondwanan faunal affinities.
