Download or read book Systematics and the Fossil Record written by Andrew B. Smith and published by John Wiley & Sons. This book was released on 2009-07-15 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new text sets out to establish the key role played by systematics in deciphering patterns of evolution from the fossil record. It begins by considering the nature of the species in the fossil record and then outlines recent advances in the methodology used to establish phylogenetics relationships, stressing why fossil evidence can be crucial. The way species are grouped into higher taxa, and how this affects their utility in evolutionary studies is also discussed. Because the fossil record abounds with sampling and preservational biases, the book emphasizes that observed patterns can rarely be taken at face value. It is argued that evolutionary trees, constructed from combining phylogenetic and biostratigraphic data, provide the best approach for investigating patterns of evolution through geologic time. The only integrated text covering the study of evolutionary patterns from a phylogenetic stance.

Download or read book Echinoids from the Triassic St Cassian of Italy Their Lantern Supports and a Revised Phylogeny of Triassic Echinoids written by Porter M. Kier and published by . This book was released on 1984 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three new species of Triassic echinoids are described from the St. Cassian (Karnian) beds of Cortina d'Ampezzo, Italy: Levicidaris furlani, L. pfaifferi, and Zardinechinus giulinii. Hundreds of echinoid fragments from the same beds show that 16 species lack apophyses (interambulacral lantern supports) and 7 possess them. Previously, paleontologists assumed that most Triassic echinoids had apophyses. Their absence from so many species and the presence of slightly developed auricles (ambulacral lantern supports) suggest that two echinoid lineages crossed from the Paleozoic to the Triassic: one, possessing apophyses, is ancestral to all modern cidaroids; a second, lacking apophyses, gave rise to all noncidaroid echinoids.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive synthesis of the range of biological information that can be retrieved from the fossilised skeletons of echinoids. The first half consists of a detailed explanation of the functional significance of skeletal structures and the inferences to be drawn from them about the living animals. This is followed by a discussion of the important evolutionary changes that have taken place and why they may have occurred. Finally, there is a section on how echinoids relate to other echinoderm groups.
