At present, these ammonites occur frequently in the Kotouč Quarry, they are richly deposited in Moravian-Silesian museums. In the past years the given family has been studied in foreign localities many times. In represented species, sexual dimorphism is observed based on different shape of mouth on microconchs and macroconchs. Summary of previous knowledge is presented aptly by Zeiss (2001). Based on the study of original material in Munich processed by Zittel (1868, 1870), specimens deposited in above-mentioned museums and our collection, 6 species in the Štramberk Limestone at Štramberk area have been revised so far. One of them represents probably a new species or a macroconch unknown yet.
The most abundant species in the Štramberk Limestone is Haploceras elimatum. As far as this species is concerned, microconchs have not been found yet. With regard to size of adult shells, it is clear that aptychi, i.e. the lower element of the jaw apparatus, occurring in body chambers of this species, belong to the genus Punctaptychus. Other representatives of haploceratids of the Štramberk Limestone belong especially to the genus Hypolissoceras. The typical representative of them is H. carachtheis. Aptychi of this genus, the shells of which reach medium size, belong to the genus Beyrichilamellaptychus.
