The Handbook of Paleoichthyology summarizes (as far as possible) all known data as a base for comparison with new findings and for interpretation of interrelationships. The reader will find the most current analysis of interrelationships, sometimes even contrary to ones in different volumes.
Each volume deals with the anatomy and the fossil record of agnathans or of a group (class, subclass, etc.) of fishes, except volume 10, which deals with one organ of osteichthyan fishes – otoliths or ear stones. We add two volumes on elasmobranch teeth: Vol. 3D Chondrichthyes (Paleozoic Elasmobranchii: Teeth) appeared in 2010, and now Chondrichthyes 3E (Mesozoic and Cenozoic Elasmobranchii: Teeth). A special volume 3C will deal with the skeletal anatomy of the Elasmobranchii. Vol. 3D Chondrichthyes (Paleozoic Elasmobranchii: Teeth) was awarded a price for outstanding accomplishment by the Polish Minister of Science and Higher Education in 2011.
Volumes 3A and 3B of the Handbook have been sold out, even a reprint of volume 3B. In addition many publications on shark teeth have been published since the beginning of the 1980s. Therefore it was decided to produce a second edition of volumes 3 (3D and 3E), to add all the new data published in recent years on elasmobranchs.
