Early Vertebrates (Oxford Mong>onong>ographs ong>onong> Geology ong>andong> Geophysics) 31. Oktober vong>onong> Philippe Janvier This book presents our current knowledge of the early vertebrates, which were mainly fish, but included some long>andong> vertebrates, ong>andong> lived about 470 to 250 milliong>onong> years ago. It centres ong>onong> anatomical ong>andong> phylogenetic questiong>onong>s, but includes informationg>onong> about fossil discovery ong>andong> preparationg>onong>, as well as the analysis of the characteristics from which their relationg>onong>ships may be recong>onong>structed. It addresses critically both old ong>andong> new problems in the evolutiong>onong> of certain anatomical structures ong>andong> deals briefly with the animals' way of life, extinctiong>onong>, ong>andong> former distributiong>onong>. In additiong>onong>, the author gives a potted history of the field of vertebrate palaeong>onong>tology ong>andong> the rise of cladistics, a major methodological revolutiong>onong> in comparative biology. The book is the first in theif field to use a cladistic approach. For each major vertebrate group, the reader will find a diagram of relationg>onong>ships, or cladogram, with a selectiong>onong> of characters at each node, ong>andong> a cuccinct phylogenetic classificationg>onong>. The book is illustrated with numerous line drawings, culminating in a series of recong>onong>structiong>onong>s of early vertebrates ong>andong> their environg>onong>ment, which may have a more popular appeal. This book is intended for palaeong>onong>tologists, geologists, vertebrate biologists. · Gebundene Ausgabe: 393 Seiten · Verlag: Oxford University Press (31.
