| Abstract |
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 all carcharhiniform genera and families. Dental morphology, histology and vascularisation results allow to provide an odontological key to all supraspecific taxa of this order and suggest a number of systematical adjustments. The glossary for the series, as published so far, has been complemented and updated. |
