      More Details Abstract Fulltext PDF

      A new genusBosostrea and its five species are described. Among other oyster species already known from elsewhere but now found occurring in the Bagh Beds,Cameleolopha cameleo (Coq.) is of particular interest bearing on the age of these beds as it comes from the Cenomanian of Algeria, andLopha (Actinostreon) semiplana (Sow.) is of interest as a species widely occurring in the Mediterranean Palaeo-Zoo-Geographic Province.

    • Taxonomic comments on subfamily Ostreinae Rafinesque

      In the light of the present authors’ work on subfamily Ostreinae from the Cretaceous of India, it was felt desirable that the two informal groups non-incubatory and incubatory genera of Stenzel in this Subfamily, be raised to the status of tribes as Crassostreini and Ostreini respectively on par with tribe Flemingostreini Stenzel. Also two new non-incubatory generaCussetostrea andSoleniscostrea are proposed here based on the type species asCrassostrea cusseta Sohl and Kauffman andCrassostrea soleniscus (Meek) respectively.

    • Remarks on the fossil genusVultogryphaea Vyalov (Pelecypoda: Mollusca) with description of a new species from Cretaceous beds of South India

      Presence of orbicular muscle mark close to hinge margin and typical exogyriid ligamental area characterised by twisted nature, indistinct anterior bourrelet and sharp-crested posterior bourrelet as revealed in our recently acquired material confirms placement of the genusVultogryphaea Vyalov to subfamily Exogyrinae as proposed by Stenzel. New speciesVultogryphaea erumanurensis comes from Erumanur, Vriddachalam area, Tamil Nadu. The present material takes the time range of the genus to Maestrichtian.

    • Revision of Cassiduloid genusGongrochanus Kier (Echinodermata: Echinoidea) from South Indian Cretaceous deposits

      More Details Abstract Fulltext PDF

      Revision of the genusGongrochanus Kier from Upper Cretaceous beds of South India has revealed the presence of seven species including its type speciesG. herschelianus (M’Clelland). On the basis of phyllode characters the species have been divided into two informal groups. A biometrical analysis by applying the Bartlett’s andF-test proves the validity of the species described. Coefficients of correlation and regression computed for parameters of length, width and height forG. herschelianus are dependent upon one another; that change of length versus width is more regular than that of length versus height. Occurrence of this genus inHauriceras rembda zone andPachydiscus otacodensis zone of Kallankurichchi and Ottakkovil formations respectively of Ariyalur Group helps in rectifying its geological age which now can be taken as extending from Lower Maestrichtian to Middle Maestrichtian instead of Senonian.
