Majidifard M.R. (2015) Late Bajocian-Bathonian ammonites from Northeast Iran // Acta Palaeontologica Romaniae. V. 11. no.2. P. 25-41

http://www.geo-paleontologica.org/actapal....ard.pdf

The present study is the first part of a larger work concerning the systematic descriptions of the fairly rich Middle to Upper Jurassic (Late Bajocian–Early Tithonian) ammonite fauna from the northeast of Iran. The described ammonites come from the lower part of the Dalichai Formation, consisting of an alternation of green marl, grey limestone and marly limestone, and comprise the families Phylloceratidae, Spiroceratidae, Oppeliidae, Sphaeroceratidae, Stephanoceratidae, Tulitidae, Parkinsoniidae, Morphoceratidae and Perisphinctidae. Some of the taxa are recorded for the first time from Iran: Adabofoloceras subobtusum, Spiroceras cf. orbignyi, Spiroceras annulatum, Cadomites (Polyplectites) cf. dorni, Sphaeroceras tutthum, Garantiana (Orthogarantiana) cf. densicostata, Garantiana (Pseudogarantiana) dichotoma, Morphoceras egrediens, Microbajocisphinctes cf. pseudointerruptus, Homoeoplanulites (Homoeoplanulites) cf. bugesiacus, Homoeoplanulites (Parachoffatia) arkelli. The following Upper Bajocian to Lower Bathonian ammonite zones are present: Niortense, Garantiana, Parkinsoni, Zigzag, Retrocostatum and Discus. Palaeobiogeographically, the described ammonite fauna is closely related to those from the Sub-Mediterranean Province of the northwestern Tethys.
