Additions aux Faunes de Sélaciens du Crétacé du Texas (Albien Superieur-Campanien)

The study of several faunas from the Texas Cretaceous ranging from Albian to Campanian reveals the occurrence of 63 species, 12 of which are new: Dallasiella willistoni nov. gen. nov. sp., Protolamna carteri nov. sp., Protolamna roanokeensis nov. sp., Scyliorhinus arlingtonensis nov. sp., Scyliorhinus taylorensis nov. sp., Rhinobatos lobatus nov. sp., Rhinobatos kiestensis nov. sp., Rhinobatos ladoniaensis nov. sp., Sclerorhynchus priscus nov. sp., Sclerorhynchus fanninensis nov. sp., Texatrygon copei nov. gen. nov. sp., and Enantiobatis tarrantensis nov. gen. nov. sp.

Some of these new species, as well as other ones previously defined, belong to new genera: Dallasiella nov. gen., Cenocarcharias nov. gen., Kiestus nov. gen., Texatrygon nov. gen., and Enantiobatis nov. gen.

According to the stratigraphic range of the fossils, several faunal associations characteristic for a stage can be recognized. During the Albian, the fauna is characterized by Paraisurus macrorhiza, Protolamna roanokeensis nov. sp., Leptostyrax macrorhiza and Squalicorax sp. 1.

In the Cenomanian, the fauna is much more diversified; besides dominating species such as Carcharias amonensis, Ptychotrygon slaughteri and Pseudohypolophus mcnultyi, one can collect Protolamna carteri nov. sp., Cenocarcharias tenuiplicatus, Microcorax crassus, Squalicorax baharijensis, Scyliorhinus arlingtonensis nov. sp., Onchopristis dunklei and Enantiobatis tarrantensis nov. gen. nov. sp.

During the Turonian, the faunas are less diversified on the whole and really characteristic species are few; the genus Squalicorax is particularly well represented mainly by Squalicorax sp. (group falcatus) and S. curvatus.

At the Turonian-Coniacian boundary, faunas are again varied and characteristic taxa are more numerous: Dallasiella willistoni nov. gen. nov. sp., Protolamna compressidens, Squalicorax falcatus, S. sp. 1, S. sp. 4, Pseudocorax aff. granti, Scapanorhynchus sp., Chiloscyllium greeni, Rhinobatos kiestensis nov. sp., R. lobatus nov. sp., Ischyrhiza schneideri, Sclerorhynchus priscus nov. sp., Kiestus texanus, Ptychotrygon triangularis and Cretomanta canadensis.

During the Campanian, the fauna becomes poor, but still contains typical species: Pseudocorax granti, Squalicorax kaupi (this latter occuring up to the Maastrichtian), Scyllorhinus taylorensis nov. sp., Rhinobatos ladoniaensis nov. sp., Sclerorhynchus fanninensis nov. sp., Ptychotrygon aff. blainensis and Texatrygon copei nov. gen. nov. sp.

Many taxa, because of their narrow stratigraphical range, are particularly interesting for correlative purposes; the large geographical range of some associations such as the Cenomanian one, whose elements occur also in Africa and Europe, can be demonstrated.


Neoselachier (Pisces, Elasmobranchii) aus der Unterkreide (unteres Barremium) von Galve und Alcaine (Spanien, Provinz Teruel)


Lower Cretaceous (lower Barremian) deposits of two close localities in the Province of Teruel in North-Eastern Spain have yielded teeth of thirteen neoselachian species, four of which are new: Heterodontus carerens n.sp., Cantioscyllium alhaulfi n.sp., "Rhinobatos" incidens n.sp. and Celtipristis herreroi n. gen. n. sp. One new genus is errected: Celtipristis n. gen. Three species are identifiable only on generic level: Cretolamna sp., Carcharias sp. and Onchopristis sp. The remaining six species were already known: Protolamna sp. cf. P. sokolovi Cappetta 1980, Protoscyliorhinus lamaudi Biddle & Landemaine 1988, Spathobatis halteri (Biddle & Landemaine 1988), "Rhinobatos" picteti Cappetta 1975, Pseudohypolophus mcnultyi (Thurmond 1971) and Onchopristis dunklei McNulty & Slaughter 1962. This is the oldest known neoselachian fauna from Spain. The fauna allows to extend geographic and stratigraphic range of all species. The association is indicative of shallow marine environment.
