Abstract

Seven taxa of gastropods are described from the Ordovician (Caradoc) upper Katkoyeh Formation of the Kerman region, east-central Iran.Three are named species and four are under open nomenclature. The most abundant is the minute bellerophontiform Tritonophon peeli Horny´,1977, indicative of a shallow water plectonotid community. Shell material is not preserved in this species, but a small, simple bulbous protoconch ispresent. Two new species are Slehoferia pachyta and Nonorios kleistos, both with prominent thick-shelled conchs. Shell repair is documented inboth of these forms, interpreted as a result of failed predation. Other micromorphic species occur in the samples, but only Tropidodiscus sp. andNonorios? sp. are named. The Kerman assemblage is comparable directly with similar, closely coeval faunas in Bohemia, France, Portugal,Morocco, and Italy, corresponding with the Palaeozoic Mediterranean Province of northern peri-Gondwana.
