Abstract

This monograph deals with the morphology of the teeth and dermal denticles of the recent and fossil squalomorph sharks of the orders CHLAMYDOSELACHIFORMES and ECHINORHINIFORMES. Up to now the family CHLAMYDOSELACHIDAE has been placed under the order HEXANCHIFORMES and the family ECHINORHINIDAE under the order SQUALIFORMES. Based on tooth morphology the CHLAMYDOSELACHIFORMES and ECHINORHINIFORMES, both as separate orders, are contrasted with the orders HEXANCHIFORMES (with a new family EONOTIDANIDAE and a new genus Eonotidanus), with the SQUALIFORMES and the PRISTIOPHORIFORMES. In the systematic part all known and nine new species are described and illustrated in detail under tooth-morphological aspects with special respect to the various forms of heterodonty.
