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.
