{"title":"Two new neoselachian sharks (Elasmobranchii, Neoselachii, Synechodontiformes) from the Rhaetian (Late Triassic) of Europe","authors":"Detlef Thies, J. Vespermann, Jutta Solcher","doi":"10.1127/PALA/303/2014/137","DOIUrl":"https://doi.org/10.1127/PALA/303/2014/137","url":null,"abstract":"Two new Late Triassic shark species (Synechodus seinstedtensis sp. nov., Parascylloides turnerae gen. nov. sp. nov.) belonging to the extinct order Synechodontiformes Duffin & Ward, 1993 (Chondrichthyes, Elasmobranchii, Neoselachii) are described on isolated oral teeth from Rhaetic deposits of North Germany and England.The term “polyhemiaulacorhize” is introduced for the synechodontiform type of root architecture in order to replace the misleading term “pseudopolyaulacorhize”. The teeth of Parascylloides turnerae gen. nov. sp. nov. were identified previously as symphyseals or parasymphyseals of Rhomphaiodon minor (Agassiz, 1837). They are considered here as belonging to a different, new species because of their frequency and their morphological differences to other Triassic neoselachian teeth. The teeth of both new species show a triple-layered enameloid microstructure consisting of an external shiny-layered enameloid (SLE), a middle parallel-bundled enameloid (PBE) and an internal tangled-bundled enameloid (TBE). In Synechodus seinstedtensis sp. nov. the PBE contains probably radial bundles of apatite cristallites whereas these are lacking in the PBE of Parascylloides turnerae gen. nov. sp. nov.. The systematical significance of the presence or absence of radial bundles in the PBE remains unclear. Zusammenfassung Anhand von Zähnen aus obertriaszeitlichen Rhät-Ablagerungen von Norddeutschland und England werden zwei neue Haiarten (Synechodus seinstedtensis sp. nov., Parascylloides turnerae gen. nov. sp. nov.) aus der ausgestorbenen Ordnung Synechodontiformes Duffin&Ward, 1993 (Chondrichthyes, Elasmobranchii, Neoselachii) beschrieben. Für die Charakterisierung derWurzelmorphologie synechodontiformer Zähne wird der Begriff „polyhemiaulacorhiz“ an Stelle des irreführenden älteren Terminus „pseudopolyaulacorhiz“ eingeführt. Die Zähne von Parascylloides turnerae gen. nov. sp. nov. wurden zuvor als Symphysenoder Parasymphysenzähne von Rhomphaiodon minor (Agassiz, 1837) angesprochen, werden hier jedoch aufgrund ihrer Häufigkeit und morphologischen Eigenart einer neuen Haiart zugeordnet. Der Zahnschmelz ist in beiden neuen Arten dreilagig aufgebaut und besteht aus einer äußeren Glanzschicht (SLE), einemmittleren parallelfaserigen Schmelz (PBE) und einem inneren wirrfaserigen Schmelz (TBE). Der parallelfaserige Schmelz zeigt in beiden Arten vertikale, oberflächenparallele Fasern aus Apatit-Kristalliten. Während im PBE von Synechodus seinstedtensis sp. nov. wahrscheinlich auch radiale Faserzüge vorhanden sind, fehlen diese im PBE von Parascylloides turnerae gen. nov. sp. nov. Die systematische Bedeutung des Vorhandenseins oder Fehlens von radialen Faserzügen im PBE, ein Phänomen, das auch bei anderen triassischen Neoselachiern beobachtet werden kann, bleibt unklar.","PeriodicalId":56099,"journal":{"name":"Palaeontographica Abteilung A-Palaozoologie-Stratigraphie","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2014-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86501041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A prominent specimen of the Kerassia collection, a well-preserved rhinocerotid skull with associated mandible, is described herein. The specimen demonstrates the diagnostic cranial, mandibular, and dental characters of the genus Acerorhinus, but it is distinct enough in several anatomical aspects from the known samples of this genus to justify the establishment of a new species, A. neleus. It is characterised by the absence of horns, dolichocephaly, a moderately concave dorsal cranial profile, closely converging parietal crests, a relatively high-positioned orbit, a markedly robust zygomatic arch, a bell-shaped occipital outline, and a robust mandible. Its strong but relatively narrow mandibular symphysis has a short diastema, a concave ventral surface, and bears a pair of moderate-sized second lower incisors suggesting a female individual. The salient features of the upper dentition include a proportionally long premolar section and traces of a thin cement coating on the labial wall of the ectolophs. The upper premolars are characterised by the presence of a faint protocone constriction and a strong lingual cingulum, whereas the upper molars by the absence of lingual cinguli and the presence of a moderate protocone constriction. Clusters of numerous borings on the specimen’s surface were attributed to bioerosion induced by dermestid beetle activity. The Kerassia specimen is closely related to the few known aceratheriine specimens from Pikermi and Chomateri, which are described and referred to A. neleus n. sp. The taxonomic relationships among certain Eurasian aceratheriine samples are discussed and an updated systematic list of the Acerorhinus species is provided.","PeriodicalId":56099,"journal":{"name":"Palaeontographica Abteilung A-Palaozoologie-Stratigraphie","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2014-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74159156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stratigraphic range and palaeogeographic distribution is given for each species. Nine species are reported from Egypt for the first time. Due to their taxonomic relevance, the microstructure of the rudist taxa has been illustrated. The bivalve fauna strongly resembles that of other Tethyan regions in southern Europe, North Africa, Middle East, and eastern South America. Therefore, most of the identified taxa have a strong Tethyan affinity. The distribution patterns of bivalves have probably been influenced by east-west directed currents during the Cenomanian. However, due to the presence of geographic barriers, extensive shallow marine shelf areas, and narrowing of the Tethys during that time, the current split up, one branch extending in a clockwise direction to southeastern Europe. The opening of the Trans-Saharan Seaway of southern Tethyan bivalves immigrated to western Africa and eastern South America.","PeriodicalId":56099,"journal":{"name":"Palaeontographica Abteilung A-Palaozoologie-Stratigraphie","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2014-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74794311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lake Rein was a shallow ephemeral lake with carbonate sedimentation. Its mollusc assemblage comprises 13 species and is dominated by planorbid gastropods in species and individual numbers, accompanied by lymnaeids and rare hydrobiids. The terrestrial assemblage consists of 35 species with Discidae, Elonidae and Helicidae as most abundant taxa along with carychiids. The terrestrial gastropods suggest moist woodland and only limited areas of open habitats; the freshwater species point to stagnant and shallow water bodies with dense vegetation and only very limited fluvial input. Many taxa are illustrated for the first time and historical mis-identifications are corrected. About one third of the species is known so far from the Rein Basin only, but the majority of the species is also known from other Middle Miocene lakes and wetlands of Central Europe. The strongest faunistic relations are indicated with the Badenian wetlands of the Paratethys Sea and the so-called Silvana-beds of Southern Germany.
