The present study has adopted an elaborate field-cum-laboratory study program including bed-by-bed sampling of different faunal groups, taxonomic study of a few selected faunas
, Unitary Association methods, diversity analyses, palynology and particulate organic matter analysis as well as diverse paleo environmental proxy data, such as d13C of carbonates and organic matter, and d18O of conodont apatite.
When the ancient supercontinent of Gondwana broke up in the early Cretaceous period about 140 million years ago, the dinosaur species that evolved on the African continent became a distinct fauna
The Vaux conodont fauna
strikingly differs in diversity and composition from coeval middle-upper Katian faunas
from the United Kingdom, such as the Sholeshook Limestone from South Wales (Ferretti et al.
We show that the rise and fall of these faunas
is indeed correlated with climatic change -- the rise or fall of global paleotemperatures -- and also influenced by other more local perturbations such as immigration events.
occurs with brachiopods and other elements, which have been described by a number of distinguished palaeontologists: the Ordovician and Silurian of Anticosti Island is famous for its fossils and quality of preservation--a good thing that it is a protected area as otherwise naturally weathered slabs would soon vanish.
The lowland faunas
of wet forests are much more complex than I had ever imagined (Lynch, 1979) and, to dissect them, even more complicated.
Other Miocene records include the modern species Ophisaurus ventralis from the late Barstovian of the Egeihoff Local Fauna
of Nebraska (Holman 1973), the extinct species Ophisaurus canadensis from the late Barstovian of the Wood Mountain Formation of Saskatchewan, Canada (Holman 1970), and the modern species Ophisaurus attenuatus from the Clarendonian of the Wakeeney Local Fauna
of Kansas (Holman 1975).
INTRODUCTION Faunal lists for the Medicine Pole Hills (MPH) Local Fauna
have been reported (1,2), however, the only element of the fauna
that has been studied in detail is the artiodactyl, Leptomeryx (3).
are contributors to this process and to the maintenance of soil fertility (Swift et al.
For many types of Australian habitats, the effect of bushfires on vertebrate fauna
is fairly well understood.
Based on their distributions (Table 1), each species is placed into one of four unionoidean faunas
associated with the five drainage systems of the southern Glacial Lake Agassiz region.
This may explain why the three models can fit both communities of forest and modern oceanic benthic faunas
