Principles of Zoological Micropalaeontology, Volume 2 highlights the morphological, phylogenetic and ecological analysis of microfossils. This book is composed of eight chapters that survey the most important microfossil taxa, their variety of form, evolution, relationships, and distribution. The first chapters describe the general morphology and characteristics of skeletal elements of main groups of sponges, melanoscleritoids, polychaetes, and conodonts. Other chapters deal with the anatomy, reproduction, ecology, phylogenetics, classification, and geological distribution of Ostracod and Echinodermata. The last chapters examine the morphological, phylogenetic, and structural aspects of class Ascidiacea and fish microfossils. This book is of great value to micropalaeontologists, zoologists, phylogeneticists, and taxonomists.
