Paleontology -- Australia
The later Cainozoic deposits of Queensland contain remains of Crocodiles
referred to _Pallymnarchus pollens_ (from Maryvale Creek) and _Crocodilus
porosus_ (from Chinchilla and Arcola, near Brisbane, Queensland). The
former species has also occurred at Clunes, whilst _Crocodilus porosus_ is
recorded from the Loddon Valley, both in Victoria. Another late Tertiary
reptile is the remarkable Horned Turtle, _Miolania oweni_, which is found
in Queensland in Pleistocene deposits (Fig. 134 D), and in the Pliocene
(Deep Leads) of Gulgong, New South Wales; whilst a second species of the
same genus, _M. platyceps_, is found in coral sand at Lord Howe Island,
400 miles distant from Australia. This genus has a skull with large bony
protuberances, giving it a horned appearance, and the tail is encased in
a bony sheath. A species of _Miolania_ is also described from Patagonia.
The Cave deposits of Wellington Valley, New South Wales, as well as the
fluviatile deposits of Queensland, have, yielded the bones of several
genera of lizards, including the Giant Lizard (_Megalania_), which, in its
length of 20 feet exceeded that of most living crocodiles.
=Birds.--=
_BIRDS (AVES)._--These warm-blooded animals are closely related to
Reptiles in many essential particulars; and are generally considered
to more nearly approach the Deinosaurs than any other group. The
Ratitae ("Raft-breasted" or keel-less birds) and Carinatae (with keeled
breast-bones), a sub-class including most modern birds, were probably
differentiated before the Cainozoic period.
=Jurassic Bird.--=
The oldest recorded bird, the remarkable _Archaeopteryx_, of the
Upper Jurassic of Bavaria in Europe, belonging to the Saururae
(Reptilian-tailed) is, so far, restricted to the beds of that age.
=Miocene Bird, New Zealand.--=
The earliest known birds in Australasia occur in the Miocene rocks (Oamaru
Series), of New Zealand. In this series, in the Marawhenua Greensands,
a Giant Penguin, _Palaeeudyptes antarcticus_ is found at Kakanui near
Oamaru, at Curiosity Shop near Christchurch and at Brighton near Nelson,
New Zealand: this interesting occurrence shows that these restricted
antarctic birds had already become an established type as early as the
Miocene.
=Victorian Cainozoic Bird.--=
The impression of a bird's feather, probably of a Wader, has lately been
described from Western Victoria (see _antea_ Fig. 16 and Fig. 135). This
occurs in ironstone, on the surface of which are also impressions of Gum
(_Eucalyptus_) and Native Honeysuckle (_Banksia_) leaves, of species
closely related to those now growing in the same locality. This ironstone
is probably of Janjukian age, and may therefore be coincident with the New
Zealand occurrence of the _Palaeeudyptes_ in the Oamaru Series.
=Pliocene Moa, New Zealand.--=
