A study of Badamu Formation brachiopoda in theNorth of Kerman (Hojedk section)
|Category||Paleontology and Stratigraphy|
|Location||21th symposium on geosciences|
|Holding Date||24 May 2008|
Brachiopoda of Badamu Formation in the Hojedk section (north of Kerman) was studied recognizing ten genera and fourteen species that are as follows:
Holcorhynchia standishensis, Conarosia sp., Baeorhynchia elegantula, Baeorhynchia nitida, Baeorhynchia transversa, Rhynchonelloidea ruthenensis, Cymatorhynchia singularis, Conarosia rotundata, Somalirhynchia arabica, Sphaeroidothyris sphaeroidalis, Sphaeroidothyris arabica, Arabicella ovalis, Plectothyris sp., Orthotoma sp.,
Based on the stratigraphical value these Brachiopoda can be classified in two biozones, the age of the first biozone based on the stratigraphical value of species Holcorhynchia standishensis is Late Toarcian and equals to Variabilis, Thouasensa and Levesquei ammonity zones. The age of the second biozone based on the stratigraphical value of their Brachiopoda is Early- Middle Bajocian, which are comprised Opalium- Humphriesianum ammonity zones. Also, frquency above of mentioned Brachiopoda were calculated which recognized Rhynchonellid order is constituted about eighty percent of them. Moreover, distribution of the Brachiopoda was studied in the various regions of the world having those the most similar with Saudi Arabia.
