Fish remains are fairly abundant in the Lower Cretaceous of Queensland. They comprise both the sharks and the ganoids. Of the sharks, a specimen, showing seven conjoined vertebrae has been named _Lamna daviesii_, from the Richmond Downs, Flinders River district; and a tooth referred to _Lamna appendiculatus_, Agassiz, from Kamileroy, Leichhardt River, N.W. Queensland. The typical Cretaceous genus _Corax_ is represented by a small tooth named _C. australis_ (Fig. 124 C), from the Hamilton River, Queensland, and which closely approaches the tooth of _Corax affinis_, Agassiz, from the Upper Cretaceous of Europe. Of the ganoid fishes two genera, both members of the family _Aspidorhynchidae_, have been found in Queensland. _Aspidorhynchus_ sp. and _Belonostomus sweeti_ (Fig. 124 D) have both occurred at Hughenden, Flinders River district. The former genus has a slender body and produced rostrum; in Europe it is more characteristic of Jurassic strata. _Belonostomus_ ranges from the Upper Oolite, Bavaria, to the Upper Cretaceous in other parts of the world. Remains of a species of _Portheus_, one of the predaceous fishes which lived in the Cretaceous period, consisting of a portion of the cranium with the anterior part of the jaws, has been obtained from the Rolling Downs Formation (Lower Cretaceous) near Hughenden, Queensland. =Cretaceous Fishes, New Zealand.--= [Illustration: =Fig. 130--CRETACEOUS and CAINOZOIC FISH-TEETH.= A--Notidanus marginalis, Davis.

New Zealand ] The Cretaceous beds of New Zealand are grouped in ascending order as the Waipara Greensands, the Amuri Limestone and the Weka Pass Stone. In the Waipara beds occur the teeth of _Notidanus marginalis_ (Fig. 130 A), and _N. dentatus_. In the Amuri Limestone _N. dentatus_ is again found, as well as the genus _Lamna_, represented by _L. compressa_, Ag. (originally described as _L. marginalis_, Davis), _L. carinata_ and _L. hectori_. Two forms of "Elephant fish" are represented by their dental plates, namely _Callorhynchus hectori_ (Fig. 130 B) and _Ischyodus thurmanni_, Pictet and Campiche (recorded as _I. brevirostris_, Ag.). =Cainozoic Fishes.--= Fish remains principally consisting of teeth, are common fossils in the Cainozoic beds of southern Australia, particularly in Victoria, and also in New Zealand. =Balcombian Series, Southern Australia.--= The Balcombian beds as seen at Mornington and in the Lower Beds at Muddy Creek, Hamilton, contain the teeth of sharks as _Odontaspis contortidens_, _Lamna crassidens_, _L. apiculata_, _Oxyrhina hastalis_ (rarely), _O. minuta_, _Carcharodon megalodon_, and _C. robustus_. =Janjukian.--=
