“…They otherwise have a poor fossil record that so far only extends back to the early Cretaceous (Thies, 1979). Pristiophoroid ancestry has been traced back to the late Cretaceous (Herman, 1975;Keyes, 1983). The fossil record of Chlamydoselachus extends into the Miocene (Leriche, 1929), late Oligocene (Phillips et al, 1976) and Middle Eocene (Pfeil, 1983).…”

Living sharks, skates and rays share several derived skeletal characters that are absent in most extinct elasmobranchs, suggesting a monophyletic group of ‘higher’ elasmobranchs. Within this group opinions vary as to phylogenetic relationships, although three broad groups are generally recognized. Arguments for and against monophyly of these group (batoids; squalomorphs; galeomorphs) are examined. Many of their contained taxa are also of questionable validity. Cladistic analysis of living galeomorphs reveals a sequence of characters supporting monophyly of the group as whole, but not of its more generalized contained taxa. The temporal distribution of fossil galeomorphs corroborates the hypothesis of relationship suggested by neontological data; i.e. there is considerable stratigraphic harmony with Recent phylogenetic data.

The published Oligocene record of mysticetes (baleen whales) is dominated by toothed mysticetes in addition to the Eomysticetidae, the earliest known chaeomysticetes known only from the Oligocene. Formally recognized eomysticetids include examples from the Oligocene of South Carolina, USA (Eomysticetus), and Japan (Yamatocetus). A new fossil from the upper Oligocene Otekaike Limestone including a partial skull, periotic, tympanic bulla, mandible and some postcrania is here described as Tohoraata raekohao gen. et sp. nov. Tohoraata confirms the presence of an eomysticetid in New Zealand. Tohoraata raekohao is characterized by delicate frontal with numerous supraorbital foramina and sulci, relatively long exposure of the frontal and parietal along a transversely narrow intertemporal region, greatly enlarged temporal fossa, massive and anteriorly directed zygomatic process lacking a supramastoid crest, and a periotic with superior process reduced to a low ridge with anterior and posterior apices. Cranial and postcranial fusion of elements, development of muscle attachments and osteohistology demonstrate that the T. raekohao holotype is an adult or possible subadult. Features of the tympanic bulla including a relatively wide bulla with a medial lobe that is transversely much wider than the lateral lobe, and a slightly posterolaterally facing exoccipital, permit referral of the fragmentary ‘Mauicetus’ waitakiensis of Marples into the genus Tohoraata, resulting in Tohoraata waitakiensis comb. nov. Description of T. raekohao and resolution of the relationships of the hitherto problematic Tohoraata waitakiensis indicates that several eomysticetids were present in the Southern Ocean during the Late Oligocene.
