Odontodes


Book Description

The odontode system, which encompasses teeth and other dentine-based structures, is ancient. Odontodes are present in the oldest vertebrate fossils, dating back 500 million years, and still play an important role in the anatomy and function of living jawed vertebrates. Fossils preserve odontode tissues with remarkable nanoscale fidelity, allowing the evolution and diversification of the odontode system to be studied in deep time as well as across the diversity of living vertebrates. This synthetic volume presents an overview of odontode research by internationally leading researchers from different fields of biology.. Key Features Summarizes classic and cutting-edge research devoted to the development and evolution Focuses on the cellular aspects of odontogenesis Documents the structural and functional diversity of odontode tissues Describes the patterning mechanisms of dentitions in various vertebrate groups Provides a thorough index for students




Paleobiology of the Williamsburg Formation (Black Mingo Group, Paleocene) of South Carolina, U.S.A.


Book Description

This is a print on demand publication. The excavation of an immense pit near the Santee River in South Carolina has produced the first Paleocene vertebrate fauna from the South Atlantic coast of the U.S., as well as a rich flora that provides extensive knowledge of the paleoenvironmental setting in which those animals flourished nearly 60 million years ago. The excavation penetrated the Late Paleocene Williamsburg Formation & yielded many specimens collected from the spoil piles, among which were the first Paleocene mammal remains from the east coast of North America. Here, eight paleobiologists interpret the discoveries systematically & compare them with Paleocene floras & faunas from elsewhere in North America & around the globe. Auhors include: Bruce Erickson (crocodilians & a snake); Robert Weems (bony fishes); Weems & Laurel Bybell (geological setting); Lucy Edwards (dinoflagellates); Robert Melchior (pollen, spores, fossil wood, & amber); Robert Purdy (sharks & rays); Howard Hutchison & Robert Weems (turtles); Robert Schoch (mammals), Glenn Sawyer (coprolites); & Erickson & Melchior (trace fossils). "One of the most significant contributions to our knowledge of early Tertiary times in this region."




Fishes and the Break-up of Pangaea


Book Description

This volume, in honour of Peter L. Forey, is about fishes as palaeobiogeographic indicators in the Mesozoic and Cenozoic. The last 250 million years in the history of Earth have witnessed the break-up of Pangaea, affecting the biogeography of organisms. Fishes occupy almost all freshwater and marine environments, making them a good tool to assess palaeogeographic models. The volume begins with studies of Triassic chondrichthyans and lungfishes, with reflections on Triassic palaeogeography. Phylogeny and distribution of Late Jurassic neoselachians and basal teleosts are broached, and are followed by five papers about the Cretaceous, dealing with SE Asian sharks, South American ray-finned fishes and coelacanths, European characiforms, and global fish palaeogeography. Then six papers cover Tertiary subjects, such as bony tongues, eels, cypriniforms and coelacanths. There is generally a good fit between fish phylogenies and the evolution of the palaeogeographical pattern, although a few discrepancies question details of current palaeogeographic models and/or some aspects of fish phylogeny.
