The Middle Paleozoic Selachian Genus Thrinacodus

  title={The Middle Paleozoic Selachian Genus Thrinacodus},
  author={Michał Ginter and Susan Turner},
ABSTRACT The late Devonian—Carboniferous (D–C) shark Thrinacodus has been known only from highly distinctive teeth since its first description from North America in 1875. The poor quality of illustrations of the type material meant that the thrinacodont tooth form remained unrecognized until the early 1980s when similar teeth were found in D–C boundary beds in Australia. Since then, Thrinacodus taxa have been found globally with a Paleotethyan distribution. Discovery of articulated specimens… 

The early elasmobranch Phoebodus: phylogenetic relationships, ecomorphology and a new time-scale for shark evolution

The first skeletal remains of Phoebodus from the Famennian (Late Devonian) of the Maïder region of Morocco are reported, revealing an anguilliform body, specialized braincase, hyoid arch, elongate jaws and rostrum, complementing its characteristic dentition and ctenacanth fin spines preceding both dorsal fins.

A critical appraisal of appendage disparity and homology in fishes

Identifying homologies of morphological traits across large phylogenetic scales is not always straightforward, as many structures are likely to have accrued changes in morphology and function over evolutionary time.
