| The description of micro-teeth within the Carcharhiniformes is hereby completed by presentation of generic representatives for the remaining families Proscylliidae, Hemigaleidae, Pseudotriakidae, Leptochariidae and Carcharhinidae. Detailed descriptions of the tooth morphology are given, as well as SEM-photographs. The tooth morphology of the genera herein concerned is compared with those published of the other carcharhiniform families in two previous issues of this series, in order to elucidate the interrelationships within this shark order also from an odontological point of view. The dental histology for the carcharhiniform genera is commented on, and their dental vascular types are re-examined. The results are summarized in a differential diagnosis for... |

| The teeth of nearly all supraspecific taxa of squaliformes are described and illustrated by SEM photos. The tooth morphology allows a direct assignment to all these taxa and some proposals of taxonomic adjustments. The results support opinions of other authors, that Echinorhinidae represent a separate order, Oxynotidae coincide odontologically with Squalidae; Squalid genera could be grouped into 8 subfamilies, 4 of which could not be defined hitherto; <i>Centroselachus</i> Garman, 1913 is confirmed and should be revalidated; significant odontological differences do not exist between <i>Cirrhigaleus</i> and <i>Squalus, Lepidorhinus</i> and <i>Centrophorus, Scymnodon</i> and <i>Scymnodalatias</i>,... |

Contributions to the study of the comparative morphology of teeth and other relevant ichthyodorulites in living supra-specific taxa of Chondrichthyan fishes. Part B. Batomorphii. 1b: Order Rajiformes - Suborder Rajoidei - Family: Rajidae - Genera and Subgenera: <i>Bathyraja</i> (with a deep-water, shallow-water and transitional morphotype), <i>Psammobatis, Raja (Amblyraja), Raja (Dipturus), Raja (Leucoraja), Raja (Raja), Raja (Rajella)</i> (with two morphotypes), <i>Raja (Rioraja), Raja (Rostroraja), Raja lintea</i>, and <i>Sympterygia</i>

| Part B, No. 1a of this series, comprising of the Batomorphii the first section on the Rajoidei, is continued with further rajoid taxa. The tooth morphology of representatives of eleven more genera and subgenera <i>Bathyraja albomaculata, Bathyraja spinicauda, Psammobatis rudis, Raja (Amblyraja) radiata, Raja (Dipturus) batis, Raja (Leucoraja) naevus, Raja (Raja) clavata, Raja (Rajella) bathyphila, Raja (Rajella) fyllae, Raja (Rioraja) agassizi, Raja (Rostroraja) alba, Raja lintea</i> and <i>Sympterygia bonapartei</i> is described and illustrated by SEM-photographs. Differential diagnoses, systematic interpretations, as well as an odontological key will be given in a forthcoming issue dealing with the last rajoid taxa. |

| The morphology of the microteeth of the following taxa is described and illustrated with SEM-photographs in order to elucidate the interrelationships within the shark orders and families concerned and also from odontological point of view. Contribution 1b: The monotypic single genus of the hexanchiform Chlamydoselachidae. The tooth morphology of <i>C. anguineus</i> is compared with that of taxa of the only other hexanchiformes. The dental histology is commented on, and the dental vascular type is re-examined in order to understand the root form. The results are summarized in an odontological diagnosis for the genus. Investigational results on dental morphology, histology and vascularization recommend a reconsideration of the systematic position... |

| Part B, Nos. 1a and 1b of this series, comprising of the Batomorphii the first and the second sections on the Rajoidei, is continued with the last group of rajoid taxa as far as material was available. The tooth morphology of representatives of eleven more genera and subgenera, namely <i>Arhynchobatis, Bathyraja richardsoni-type, Cruriraja, Irolita, Notoraja, Pavoraja (Insentiraja), Pavoraja (Pavoraja), Pseudoraja, Raja (Atlantoraja), Raja (Okamejei)</i> and <i>Rhinoraja</i>, is described and illustrated by SEM-photographs. Differential diagnoses and systematic interpretations are presented as a result of the odontological examinations described here and in the previous two issues 1a and 1b for the supraspefic taxa of the Rajoidei. |

| Part B of this series, comprising the Batomorphii, is initiated with taxa of the Rajoidei. The tooth morphology of representatives of nine genera and subgenera is described and illustrated by SEM-photographs. An adapted terminology is introduced for the description of rajoid teeth, because their tooth morphology differs markedly in various aspects from that in selachians. A differential diagnosis for and conclusions on rajoid odontology, as well as an odontological key will be given in a forthcoming issue dealing with the last rajoid taxa. |

| The tooth and rostral spine morphology of representatives of the pristid genera <i>Anoxypristis</i> and <i>Pristis</i>, of the rhinid genera <i>Rhina</i> and <i>Rhynchobatus</i> and of the rhinobatid genera: <i>Apytchotrema, Platyrhina, Platyrhinoidis, Rhinobatos, Trygonorrhina, Zanobatus</i> and <i>Zapteryx</i> is described and illustrated by SEM photographs. A differential diagnosis is given to distinguish the genera by tooth morphology. |

| With the exception of the unavailable genera <i>Heteroscyllium</i> and <i>Sutorectus</i>, this fascicle comprises the descriptions of microteeth of the genera of the orectolobiform families Brachaeluridae, Ginglymostomatidae, Hemiscylliidae, Orectolobidae, Parascylliidae, Rhiniodontidae, Stegostomatidae, of the pristiophoriform family Pristiophoridae and the squatiniform family Squatinidae. Detailed descriptions of the tooth morphology, and rostral spine morphology for Pristiophoriformes are given, as well as SEM-photographs. The tooth morphology of the genera concerned is compared in order to elucidate the interrelationships within these shark orders also from an odontological point of view. The dental histology for the... |
