The beautiful spiral shells of these long-extinct marine invertebrates
are among the most sought after and recognizable of fossils, yet little
has been published about ammonites outside of geological journals. Neale
Monks and Philip Palmer look at the latest ideas on ammonite biology and
ecology to present this detailed picture of a once diverse and
widespread group of animals.
The authors describe the evolution of ammonites and their relatives and
explain how they created their shells and used them as flotation
devices. All the major groups of ammonites are described and illustrated
(as are many minor ones), and important material is included on anatomy,
feeding, reproduction, and pathology. The 300-million-year existence of
ammonites ended at around the same time that dinosaurs became extinct.
Fortunately, ammonites were once so abundant that their fossilized
shells can be readily found, and the authors provide a helpful guide to
locating and collecting these unique fossils.
