Triassic Period
The Triassic period was
the first of three periods in the Mesozoic Era
(the others being the
Jurassic period
and the
Cretaceous period),
and occured between 248 million and 213 million years ago.
It was during the Triassic period that archosaurs ("ruling reptiles"),
including
dinosaurs, crocodiles, and
Pterosaurs first evolved.
Prior to the Triassic, during the previous Permian era, mammal-like reptiles
had been the dominant land animals. Some survived into the Triassic, but
they dramatically declined, apparently out-competed by the dinosaurs. The
mammal-like reptiles did however give rise to the first mammals, these being
tiny mouse-sized animals. The dominant plants during the Triassic period
were
conifers, ferns, ginkgos and horsetails.
Here is a map of the world during the early Triassic (about 225 million years ago).
At this time, all the continents were combined into one massive super-continent,
known as Pangaea:
The different geography of the world also led to a different climate.
On the whole, the Triassic was generally hot and dry, and there
was no glaciation or ice caps at the poles (polar regions were moist and temperate).
The interior of Pangaea would have had a highly seasonal continental climate,
with very hot summers and cold winters.
Triassic Dinosaurs
Here are some of the types of dinosaurs
that lived during the Triassic period:

Before the Age of Dinosaurs there was an age in Earth's history known as the Triassic. It was a world of truly fantastic creatures, a genetic stew of the ancient and the modern. During this time the Earth took its first steps toward the creation of modern terrestrial ecosystems. This incredibly exciting period is brought vividly to life in the words of paleontologist Nicholas Fraser and the consummate artistry of Douglas Henderson. Together they have created a book in which the riches of Triassic life are presented with clarity, scientific accuracy, and imaginative recreation. Every lover of the life of the past will treasure Dawn of the Dinosaurs. "Fraser (curator, vertebrate paleontology, Virginia Museum of Natural History) has prepared a serious work on Triassic paleontology. The text is accompanied by numerous color plates of animals and scene reconstructions as well as quality line drawings and illustrations... The book itself is rather readable and represents a comprehensive review of Triassic vertebrate evolution accessible to both experts in the field and generalists ... Fraser presents a comprehensive picture...A refreshing approach in a market saturated with "just so" stories and sanitized tales of evolution. Summing Up: Highly recommended. Graduate students through professionals." -- Choice May 2007 |

The Mesozoic Era begins with the approximately 50-million-year-long Triassic Period, a major juncture in Earth history when the vast Pangaean supercontinent completed its assembly and began its fragmentation, and the global biota diversified and modernized after the end-Permian mass extinction, the most extensive biotic decimation of the Phanerozoic. The temporal ordering of geological and biotic events during Triassic time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is mostly based on the Triassic timescale, which has been developed and refined for nearly two centuries. This book reviews the state of the art of the Triassic timescale and includes comprehensive analyses of Triassic radio-isotopic ages, magnetostratigraphy, isotope-based and cyclostratigraphic correlations and timescale -relevant marine and non-marine biostratigraphy.The Geological Society of London Founded in 1807, the Geological Society of London is the oldest geological society in the world, and one of the largest publishers in the Earth sciences. The Society publishes a wide range of high-quality peer-reviewed titles for academics and professionals working in the geosciences, and enjoys an enviable international reputation for the quality of its work. The many areas in which we publish in include: -Petroleum geology
-Tectonics, structural geology and geodynamics
-Stratigraphy, sedimentology and paleontology
-Volcanology, magmatic studies and geochemistry

The Triassic period is generally viewed as the beginning of the Age of Dinosaurs. For paleontologists, however, it also marks the rise of the world's first modern land ecosystems. Over the past three decades, extensive, worldwide fieldwork has led to the discovery of many new species of Triassic animals and plants, suggesting that faunal and floral changes already began in the Middle Triassic and were more protracted than previously thought. The Late Triassic is a pivotal time in the evolution of life on land, with many of the major groups of present-day vertebrates and insects first appearing in the fossil record. This book provides the first detailed overview of life on land during the Triassic period for advanced students and researchers. Noted vertebrate paleontologists Hans-Dieter Sues and Nicholas C. Fraser also review the biotic changes of this period and their possible causes. |

Product Description:
This was the age of early amphibians and reptiles, lasting roughly from 248 to 206 million years ago.
Prehistoric World Books combine dramatic, scientifically accurate color illustrations with a wealth of factual details based on archaeological findings to give young readers a vivid picture of the exotic succession of animals that inhabited the Earth in the prehistoric era. Dating back to perhaps 300 million years ago, with the earliest-known life forms, the six titles in this series carry the history of animal life forward to man-like creatures such as homo erectus, and finally to prehistoric homo sapiens, or human beings like ourselves, whose origins date back an estimated 200,000 years. Individual species are presented on two-page spreads that show large illustrations of the animal when it was alive, photos of reconstructed fossil skeletons, and a list of descriptive factual details. These books are great sources for elementary school class projects, or simply for fun reading. |

Permian and Triassic rocks in the Eastern Tethyan (Southern Asia) region form continuous marine sequences that record the waning phases of the Paleozoic and the early stages of the Mesozoic eras. This period is important geologically, because during it a great number of organisms became extinct. This book describes and interprets these rocks, summarizing the distribution of major fossil groups in a way that will allow detailed comparison with strata of comparable age in the western Tethys and other parts of the world, notably European and Australian strata. The sixteen contributions by forty authors are the culmination of the five-year long International Geological Correlation Programme Project 203. The detailed information presented here is gathered from many areas in the eastern Tethyan region and will be of use in the evaluation of the major changes in the global marine biosphere known to have taken place at the end of the Paleozoic era. |

"Dawn of the Dinosaur Age" presents the first act in the drama that would become the Mesozoic Era, the Age of Reptiles. The rise of the first dinosaurs is the story of opportunity and evolutionary innovation. The first dinosaurs, after living in the shadows of larger, more dominant reptilian kin, took advantage of major mass extinctions at the end of the Triassic Period to take over niches once occupied by their predecessors. In the course of doing so, dinosaurs quickly radiated to widespread geographic ranges and began an evolutionary course that led to the development of two major groups of dinosaurs, the Saurischia and Ornithischia.The Late Triassic and Early Jurassic Periods were a time of experimentation in dinosaur evolution as the earliest herbivorous and predaceous dinosaurs adapted increasingly specialized body forms and lifestyles. "Dawn of the Dinosaur Age" explores the roots of the dinosaur family tree and the lifestyle and radiation of the first carnivorous and herbivorous dinosaurs. |

Sandstone aquifers are common worldwide: they contain a significant proportion of the Earth's fresh water supplies. However, because of their textural complexity and the frequent occurrence of both matrix and fracture flow, prediction of flow and pollutant migration is still a considerable challenge. This volume contains a collection of papers summarizing current research on an example sandstone aquifer: the UK Permo-Triassic Sandstone sequence. These red bed, organic-poor sandstones are of fluvial and aeolian origin, are often strongly textured, and are cut by discontinuities of a wide range of permeabilities. Matrix flow often dominates, but fracture flow also occurs. The papers in the volume deal with research on saturated and unsaturated flow, and solute and non-aqueous-phase liquid movement. They cover investigations from laboratory to regional scale, and involve a wide range of approaches, from petrophysical through geophysical and hydrochemical to modelling. The book is intended to be of interest to researchers and practitioners involved in water resources and groundwater pollution, and to hydrogeology, water engineering, and environmental science students.Also available: 200 Years of British Hydrogeology - ISBN 1862391556
