From the Sülstorf Beds (Chattian, Late Oligocene) of the Southeastern North Sea Basin, Northern Germany
ARTICLE Two new scyliorhinid shark species (Elasmobranchii, Carcharhiniformes, Scyliorhinidae), from the Sülstorf Beds (Chattian, Late Oligocene) of the southeastern North Sea Basin, northern Germany THOMAS REINECKE Auf dem Aspei 33, D-44801 Bochum, Germany E-mail: [email protected] Abstract: Based on isolated teeth two new scyliorhinid shark species, Scyliorhinus biformis nov. sp. and Scyliorhinus suelstorfensis nov. sp., are described from the Sülstorf Beds, early to middle Chattian, of Mecklenburg, north-eastern Germany. They form part of a speciose assemblage of nectobenthic sharks and batoids which populated the warm-temperate to subtropical upper shelf sea of the south-eastern North Sea Basin.

Paleogene Origin of Planktivory in the Batoidea
Paleogene Origin Of Planktivory In The Batoidea CHARLIE J. UNDERWOOD, 1+ MATTHEW A. KOLMANN, 2 and DAVID J. WARD 3 1Department of Earth and Planetary Sciences, Birkbeck, University of London, UK, [email protected]; 2 Department of Ecology and Evolutionary Biology, University of Toronto, Canada, [email protected]; 3Department of Earth Sciences, Natural History Museum, London, UK, [email protected] +Corresponding author RH: UNDERWOOD ET AL.—ORIGIN OF PLANKTIVOROUS BATOIDS 1 ABSTRACT—The planktivorous mobulid rays are a sister group to, and descended from, rhinopterid and myliobatid rays which possess a dentition showing adaptations consistent with a specialized durophageous diet. Within the Paleocene and Eocene there are several taxa which display dentitions apparently transitional between these extreme trophic modality, in particular the genus Burnhamia. The holotype of Burnhamia daviesi was studied through X-ray computed tomography (CT) scanning. Digital renderings of this incomplete but articulated jaw and dentition revealed previously unrecognized characters regarding the jaw cartilages and teeth. In addition, the genus Sulcidens gen. nov. is erected for articulated dentitions from the Paleocene previously assigned to Myliobatis. Phylogenetic analyses confirm Burnhamia as a sister taxon to the mobulids, and the Mobulidae as a sister group to Rhinoptera. Shared dental characters between Burnhamia and Sulcidens likely represent independent origins of planktivory within the rhinopterid – myliobatid clade. The transition from highly-specialized durophagous feeding morphologies to the morphology of planktivores is perplexing, but was facilitated by a pelagic swimming mode in these rays and we propose through subsequent transition from either meiofauna-feeding or pelagic fish-feeding to pelagic planktivory. -

A new Hybodus site from Romania is located at Anina, in the Pliensbachian – Middle Toarcian succession from Ponor quarry (Caraş-Severin district).

Journal of Fisheries 7(1): 681–684. Abstract The knifetooth sawfish Anoxypristis cuspidata (Latham, 1794) is a species of sawfish belonging to the family Pristidae. It is an Indo-West Pacific species occurring from the northern Persian Gulf to Australia and north to Japan. The species is assessed as Endangered in the IUCN Red List of Threatened Species. Main threats to the species are fishing, coastal development and habitat degradation. This sawfish species has considerable ecological importance for the regions, but there are little data of its populations. Hence, a detailed study of population status, ecological and biological characteristics of A. cuspidata is required. This study will provide basic information on distribution, biological characteristics and conservation of this species. Keywords: Knifetooth sawfish; Anoxypristis cuspidata ; threatened fish; conservation.
