Two fossil shark teeth (Galeorhinus and Physogaleus), recorded from Lower Eocene sediments of the Khuiala Formation Jaisalmer Basin, are being described and illustrated. This is the first record of Physogaleus from the Jaisalmer Basin. The record of Galeorhinus from the Jaisalmer Basin suggests subtropical sea condition during Early Eocene time.

A recently discovered selachian fauna is presently described from Chattahoochee County, Georgia in the United States of America. The authors are presenting a faunal assemblage of selachians found in an ancient oyster bed in the lower member of the Eutaw Formation. The following new taxa are described: Pseudohypolophus ellipsis nov. sp., Microdontas...

Recent discoveries of Upper Cretaceous selachian remains from the Coleraine Formation which overlies the Taconite beds of the Mesabi Iron Range in northeastern Minnesota, approximately 65 miles from the Canadian border, have given us a total of ten species, two of which are new to science. The two new species are: Hybodus rajkovicki n. sp. and Prot...

A recently discovered selachian fauna is presently described from Central Asia in the Commonwealth of Independent States (formerly the Union of Soviet Socialist Republics). Only two new taxa are described belonging to two different families of the Order Myliobatiformes: Dasyatidae: Glikmania tamdyensa nov. gen. et nov. sp.; and in the family Myliob...

Recent discovery of a fossiliferous layer in the Early Paleocene (Montian Stage), Lower Hornerstown Formation, has brought to light a fauna of sharks, skates, and chimaeras, previously unknown or reported from North America. The following new taxa are described: Dasyatis crosswickense nov. sp.; Hypolophites hutchinsi nov. sp.; and Viperecucullus ku...
Article
A puzzling new genus and species of primitive alethinophidian snake, Tuscahomaophis leggetti, is described on the basis of vertebrae from the late Paleocene Tuscahoma Formation of Meridian, Mississippi. Tuscahomaophis has characters that indicate relationships to the Palaeophiidae and, to a lesser extent, the Nigerophiidae and distinguish it from o...

WE DESCRIBED a Late Cretaceous fish fauna from the Campan-ian-age Blufftown Formation in western Georgia (Case and Schwimmer, 1988), including 15 selachian taxa and 8 osteich-thyans; however, at that time no chimaeras had been found in the region. A well-preserved specimen of Ischyodus bifurcatus Case, 1978, was subsequently collected from the same...

Seventeen figured chondrichthyan specimens are here described from the Tupelo Tongue of the Coffee Sand (Campanian) of the Upper Cretaceous of Lee County, northeastern Mississippi, Numerous additional specimens, which were not figured, were present in the collection examined. The fauna represents 11 taxa. -from Author

Mississippi has twice as many palaeopheid snakes as any other state and all four species that occur in North America: Palaeophis casei, P. littoralis, P. virginianus, and Pterosphenus schucherti. P. casei is diminutive, P. littoralis is medium-sized, and the latter two species are giant snakes. From an evolutionary standpoint Pterosphenus is more d...

A diverse assemblage of palaeopheid fossils from four Eocene sites of the Gulf Coastal region has yielded Pterosphenus schucherti Lucas and three species of Palaeophis: P. casei Holman, P. littomlis Cope, and P. virginianus Lynn.

Toothplates of the ratfish Ischyodus are rather common fossils, distributed throughout the Campanian-Maestrichtian of New Jersey and Delaware although heretofore unrecognized or described.

Research undertaken in several Cretaceous layers of New Jersey permited to list a rich selachian fauna. Especially, the upper Campanian layers of Hop Brook and Willow Brook gave us, after washing and sifting, an interesting microichthyofauna and macrofauna. Among the 28 species identified, 10 were previously unknown: Lonchidion babulskii n. sp., Pl...
