چکیده مقاله :
To study the Bryozoa and the stratigraphy of Permian rocks in the Bazman region an east-west stratigraphic section was studied. The Sarab section, which takes its name from the Sarab River, is located on the southern slope of the Bazman Volcano. The rocks of this section with a thickness of 202 m. are divided into 7 informal rock units, where the lower boundary has discordance with carboniferous sediments, and the upper boundary is faulted. Based on the microfossils and the Bryozoa, the age of the lower part of the Jamal Formation is Bolorian. In this study, three genera and species were identified, one of which has been reported for the first time in Iran. Fistulipora timorensis ( Bassler 1929), * Strablascopora cf. germana (Bassler 1929) *Filiramoporina sp., Streblotrypa ( Streblascopora)marmionensis (Etheridge 1926).
