Biological Consequences of Plate Tectonics

This book recognizes and celebrates the contributions of Professor Ashok Sahni to the field of paleontology. Prof. Sahni established a School of Vertebrate Palaeontology at Panjab University, Chandigarh, India, where he trained many of today's vertebrate paleontologists of India. The book covers topics on evolutionary patterns, macroevolutionary events, origination and radiation events, changes in physical environments & climate and their implications for biodiversity dynamics, intercontinental affinities and biogeographic connections in a plate tectonic framework.

The book begins by exploring India in the age of the dinosaurs, discussing new fossil remains from the Jurassic Era, then moves through the Cretaceous and Eocene to provide a picture on faunal and floral changes in Gondwanaland in the context of plate tectonics. Furthermore, the book explores the evolutionary patterns and biotic dispersals that resulted from the northward drift of Indian plate during the Cretaceous and its collision with Asia in the Eocene. The respective chapters reveal the role of plate tectonics and climate in shaping the geographical distribution of plants and animals in Gondwana, specifically in India, as well as the post-India/Asia collision implications for biodiversity changes and biogeography in the region's continental environments. Given its scope, the book will appeal to vertebrate paleontologists, evolutionary biologists, and paleobiogeographers.

Acknowledges and celebrates the contributions of leading India vertebrate paleontologist Dr. Ashok Sahni Explores biodiversity changes, evolutionary patterns, and changes in physical environments and climate due to shifting plate tectonics Describes the role of plate tectonics in shaping the Indian climate Discusses the paleobiogeographic history of India, including collision tectonics and biodiversity implications

Auteur

Dr. Guntupalli V.R. Prasad received his Ph.D. from Panjab University, Chandigarh in the year 1986. He is a former Professor at the University of Jammu and Indian Institute of Science Education & Research (Kolkata). He is presently a Professor in the Department of Geology, University of Delhi, India. Prof. Prasad has more than 34 years teaching experience at Graduate and undergraduate level. A vertebrate paleontologist by training, he has been working for the last three and half decades on the evolution of Mesozoic vertebrates of India using form and function of vertebrate fossils. Prasad s research has focused primarily on biodiversity changes during the time span of Deccan volcanism which brought many new species of fishes, amphibians, reptiles and mammals to light and also provided paleontological constraints on the age of initiation and duration of Deccan Volcanism. His research has also thrown light on faunal dispersals and biogeographic linkages between the physically isolated and rapidly northward drifting Indian plate and other landmasses. Dr. Prasad s findings of diverse mammalian groups from the Jurassic and Cretaceous of India have firmly placed India on Mesozoic mammalian map of the world. Author of more than 100 scientific papers published in leading journals in his field of specialization as well as high impact journals like Nature, Science, Nature Communications, and Proceedings of National Academy of Sciences, Prof. Prasad received Shanti Swarup Bhatnagar Prize, Indiäs highest science award, for his outstanding contributions in the field Vertebrate Paleontology. Other recognitions received by Prof. Prasad include J.C.Bose National Fellowship, National Geoscience Award, L. Rama Rao Birth Centenary Award, and National Award in Geosciences & Technology. He has been honored with the Fellowship of the Indian National Science Academy (FNA), Indian Academy of Sciences (FASc.), National Academy of Sciences (FNASc.), and Academy of Sciences for the Developing World (TWAS). Dr. Rajeev Patnaik did his Ph.D at Panjab University, Chandigarh and Post-Doctoral fellowships at Paläontologische Museum München, Ludwig-Maximilians-Universität, Germany and Institut des Sciences de l'Evolution de Montpellier, France. By integrating aspects of stable isotopes, microwear, morphometrics, cladistics and enamel microstructure, he has been able to contribute towards the understanding of diet and evolution of some Indian fossil mammals such as murine rodents and primate/hominins. He has also worked on the impact of climate change, palaeoecology, palaeobiogeography and geological context of Indian Neogene mammals with particular focus on the hominoids. He and his colleagues discovered new hominoids/primates, ostrich-like eggshells, new pelican and darter fossils from the Siwaliks (subhimalaya); Late Cretaceous rice from central India; and Miocene mammals from the Baripada Beds of Odisha. He has published over 100 research papers in reputed journals and has served as Associate Editor for scholarly journals such as Journal of Human Evolution, Current Science and Journal of the Geological Society of India. In 2016 he was awarded the prestigious National Geoscience Award by the Honourable President of India and in 2019 was elected as a Fellow of the Indian Academy of Sciences.

Résumé

"This volume is a welcome contribution to a palaeontologist's library. It provides a good synthesis on the current state of palaeontology in India, offering new insights to old questions. The opus is well illustrated and the text makes for easy reading. The authors are commended for their valuable contributions. ... the volume is highly recommended for those wanting to delve into eastern Gondwana during the late Mesozoic and Paleogene."
