Major insights on distribution and more Fossils and Strata, Number 50: Lower Vertebrates From the Paleozoic presents a series of papers presented at the International Paleontological Congress's 2002 symposium on Paleozoic Vertebrates. Topics include systematics, biostratigraphy, biogeography, taphonomy, and more, covering a range of early vertebrate groups including jawless agnathans, early-jawed fishes, and Paleozoic tetrapods. These proceedings include major contributions to the field, and shed light on new aspects of Devonian fauna distribution. With contributors from seven countries, these proceedings represent the global nature of paleontology and offer new answers to questions in the field.
