Parvaneh Nejad Shirazi 2Department of Geology, Payam-e- Noor University, Shiraz, Islamic Republic of Iran Journal Article 2015 10 09 The Albian- Cenomanian (Kazhdumi Formation) sediments from northeast of Shiraz, Zagros Basin, represents a carbonate sedimentary succession and contain diverse gastropods and bivalves. Detailed studies on 80 samples of invertebrate macrofauna on two stratigraphic sections led to recognized 2 species and 5 genera of gastropods and 7 species and 13 genera of bivalves assemblages. The abscence of large gastropods and bivalves fauna and abundance of suspension-feeders indicated instability of the substrate and a  medium enrgy condition. From a palaeobiogeographic point of view, the fauna from the Kazhdumi Formation were similar to the Central Iran and North Jordan and Wadi Qena (Egypt).  https://jsciences.ut.ac.ir/article_57656_b92f77a8a1006257514d20c7046515de.pdf
