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

that lived during the Triassic period:

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. (7/19/10) |

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. |

To preserve the future of humanity itself mountaineer Roy Graham must descend deep into the species’ cryptic past. In the most perilous adventure of his lifetime he confronts Stone Age beings who set brutal, brilliant traps. Discovery of pre-hominid DNA and geological tracking over millions of years are only some of the skills Graham and his team must use to comprehend the enemies they desperately need to outwit. It’s all part of author Philip E. Bartow’s wildly inventive science fiction adventure Triassic. With plot twists as ingeniously connected as a strand of DNA, Triassic probes deep into science, technology, and history to consider what it really means to be human, all the while delivering jolt after jolt of “can’t put this book down” action and intrigue. In lush, uncharted South American canyons, military helicopters equipped with sensitive technology are disappearing without a trace. When aerial surveillance reveals nothing, the only way adventure pro Roy Graham can mine the truth is to enter the jungle on foot. When his friend Mark Stark draws him into this seemingly suicidal mission, the last thing Roy expects to land among are Stone Age creatures, or Mapinguari. As Roy and his team dig into the deep recesses of the canyons, employing sophisticated DNA identification technology to reveal the expansion of pre-human beings, their discoveries unearth horrifying connections with our own species. At the same time, Roy discovers deeply disturbing aspects of some modern individuals in his own team. Triassic delivers breath-taking physical prowess and formidable intellectual puzzle solving to keep readers tightly engaged with both plot and characters page by page. |
