carboniferous strata in the alborz mountains consist of calcareous rich fossils the main part of which is composed of rugose corals. there have been few studies carried out on corals so far. in this paper, a new subfamily, genus and eight new species of rugose corals from mobarak limestones in the central alborz mountains are introduced

thirteen species of rugose corals, belonging to nine genera are described from the givetian and lower frasnian rocks of thekhoshyeilagh formation in the eastern alborz mountains (northeastern iran). glossophyllum ceratites (goldfuss), glossophyllum sp.,keriophyllum cf. maillieuxi (tsien), pseudozaphrentis sp., temnophyllum imperfectum coen-aubert, temnophyllum occidentale hilland jell, temnophy...
members of the family laccophyllidae are small, solitary rugose corals with stratigraphic ranges from silurian to permian. among the laccophyllids, axial ends of major septa are united in an aulos and dissepiments may be absent or present. minor septa can be contratingent and sometimes are small or in some genera are absent. septa and aulos may be thick or thin. in this study, famennian rugose ...

Mesozoic-Cenozoic scleractinian corals were not derived by descent from late Paleozoic rugose corals. Rather, they probably originated from a group of Paleozoic sea anemones that survived into the Mesozoic after the extinction of the Rugosa at the end of the Paleozoic. This conclusion is based on three arguments: 1. all scleractinians have cyclic septal insertion in contrast to the serial inser...
Rugose corals are described from the lower Viséan of Donets Basin. The new coral Dorlodotidae fam. nov. and species Cyathoclisia sukhensis sp. here introduced presence genera Amygdalophyllum Ceriodotia established for first time in priority generic name Protolonsdaleia over Eolithostrotionella is discussed. rugose assemblage Basin differs those upper Tournaisian Viséan. Global regional events m...
AIMS: This lab will introduce you to the basal metazoan groups: the Porifera (sponges) and the diploblastic Cnidaria (hydroids, jellyfish, anemones, sea pens, corals, and relatives). You will see examples of the important fossil representatives of these groups: demosponges, hexactinellids, and archaeocyaths (Porifera); and the rugose, tabulate, and scleractinian corals (Cnidaria). The method of...
