Vertebrate Ichnology: Introduction, History, Methodology and Devonian-Neogene Tetrapod Tracks is a complete review and analysis of vertebrate trace fossils, including how vertebrate trace fossils inform our understanding of major evolutionary events. It covers all aspects of the vertebrate trace fossil record including tetrapod footprints, fish traces and other trails, burrows, nests and more. Each record is reviewed by prominent experts with extensive illustrations and can be used as a tool to solve problems of vertebrate biochronology and biogeography. Megabiases in the record are identified, and trace fossils applied to analysis and the understanding of major events in the evolutionary history of vertebrates.This is a useful daily reference for paleontologists and geologists; and teaching professors or other researchers working in trace fossils and related fields, including university and graduate students.

This book documents analyses of the Late Cretaceous dinosaur nesting sites of the Lameta Formation at Jabalpur, Districts Dhar and Jhabua, Madhya Pradesh; Districts Kheda and Panchmahal (Gujarat); and the Pisdura, Dongargaon and Pavna sectors in the Chandrapur Districts of Maharashtra, which are exposed in India along an east-west and central axis. In this work, special emphasis has been given to the dinosaur nesting sites of the east-central Narbada River region, including its regional geology. The work was undertaken to provide detailed information concerning dinosaur eggs, eggshell fragments, nests and clutches found in the Lameta Formation of peninsular India. Prior to the present work there had been no detailed review of systematic work on the taxonomy, and of micro- and ultrastructural studies of dinosaur eggs and eggshells from the Lameta Formation. 

The  study documents the  field and laboratory investigations that facilitated the reconstruction of the morphotaxonomy, models for the burial pattern of eggs and eggshells, taphonomic implications,and the palaeoenvironmental context and palaeoecological conditions during the Late Cretaceous at the time of the extrusion of the Deccan traps, which may have been partly responsible for the extinction of the dinosaurs. The  need to follow a parataxonomic classification for Indian dinosaur eggs and eggshell types is very apparent, and this book addresses this aspect in some detail. The emphasis on the application of parataxonomic schemes is based on the description of new oospecies and their comparison with previously known forms. The  present work has led to the recovery of numerous nests, many collapsed eggs and hundreds of dinosaur eggshell fragments from the localities situated near the east, west and central Narbada River regions. It will be of interest to academics and professional palaeontologists, and all students of dinosaurs.
