Paleozoic Ammonoids in Space and Time

  • R. Thomas Becker
  • Jürgen Kullmann
Part of the Topics in Geobiology book series (TGBI, volume 13)


Paleozoic ammonoids have attracted much less attention from professional and amateur paleontologists than Mesozoic ammonoids. Because of the Variscan folding in Europe, the classical area of investigation, Devonian and Carboniferous material from Europe is often rather poorly preserved. As a result, few collectors of the 19th and early 20th century have focused their attention on these fossils. In recent decades, however, as our knowledge of Paleozoic ammonoids has expanded, it has become more and more apparent that the evolution and systematics of Paleozoic forms are as complex as those of Mesozoic ones. For example, the number of Devonian genera rose from about 80 in the Treatise of 1957 to a present figure of more than 200.
