Enameloid microstructure of the serrated cutting edges in certain fossil carcharhiniform and lamniform sharks

Microscopy Research and Technique, 2010
AbstractThe triple‐layered enameloid organization of neoselachian teeth has proven to be a reliable systematic character of the group. This study uses scanning electron microscopy to investigate the orientation of the parallel enameloid bundles in the area of the serrated cutting edges in certain fossil elasmobranchs.

A taxonomic revision of the catshark genus Haploblepharus Garman 1913  (Chondrichthyes: Carcharhiniformes: Scyliorhinidae)

Zootaxa, 2007
This paper examines the alpha level taxonomy of the genus Haploblepharus Garman, 1913 (Chondrichthyes; Scyliorhinidae). Three species are endemic to South Africa, with one species occurring in Namibia and South Africa. Haploblepharus pictus exhibits considerable colour variation which has led to some confusion between that species and H.
