Cretaceous Period
The Cretaceous period was the final of the three periods into
which we divide the Mesozoic Era (the previous periods being
the
Triassic period,
and the
Jurassic period),
and occured between 144 million and 65 million years ago.
Many well-known types of dinosaurs
lived during the Cretaceous, including
Ankylosaurus,
Iguanodon,
Pachycephalosaurus,
Protoceratops,
Spinosaurus,
Styracosaurus,
Triceratops,
Tyrannosaurus rex, and
Velociraptor.
It was also during the Cretaceous period
that the first flowering plants
("angiosperms") began to appear, including, for example,
beech, fig and magnolia.
At the end of the Cretaceous period (known as the K-T boundary), dinosaurs, and
and a variety of other animals all suddenly became extinct.
There have been many theories proposed for why this
mass extinction
occured.

Here is a map of the world in the late Cretaceous period.
You will notice that the continents have begun to move towards
their present positions (movements which continued into the subsequent Tertiary era),
with the Atlantic Ocean opening up between Europe and North America, and India
continuing its long journey Northwards.
The Cretaceous world was cooler than it had been in the
previous
Triassic
and
Jurassic.
periods, but still warmer than that of today.
At higher latitudes snowfalls became common, although the climate generally
remained warm even at such latitudes - glaciation was
restricted only to alpine regions in high latitudes.
Meanwhile, tropical parts of the
globe were much wetter than they had been previously.

Click Here | Product Description:
In 1878, the first complete dinosaur skeleton was discovered in a coal mine in Bernissart, Belgium. Iguanodon, first described by Gideon Mantell on the basis of fragments discovered in England in 1824, was initially reconstructed as an iguana-like reptile or a heavily built, horned quadruped. However, the Bernissart skeleton changed all that. The animal was displayed in an upright posture similar to a kangaroo, and later with its tail off the ground like the dinosaur we know of today. Focusing on the Bernissant discoveries, this book presents the latest research on Iguanodon and other denizens of the Cretaceous ecosystems of Europe, Asia, and Africa. Pascal Godefroit and contributors consider the Bernissart locality itself and the new research programs that are underway there. The book also presents a systematic revision of Iguanodon; new material from Spain, Romania, China, and Kazakhstan; studies of other Early Cretaceous terrestrial ecosystems; and examinations of Cretaceous vertebrate faunas. |

This book places into modern context the information by which North American mammalian paleontologists recognize, divide, calibrate, and discuss intervals of mammalian evolution known as North American Land Mammal Ages. It incorporates new information on the systematic biology of the fossil record and utilizes the many recent advances in geochronologic methods and their results. The book describes the increasingly highly resolved stratigraphy into which all available temporally significant data and applications are integrated. Extensive temporal coverage includes the Lancian part of the Late Cretaceous, and geographical coverage includes information from Mexico, an integral part of the North American fauna, past and present. |

Click Here | Product Description: Prepare for an adventure as you experience the epic story of Iron Kombat as told by the crew team leaders themselves as they found on the island huge vicious dinosaurs and the only way to combat these monsters was to use iron monsters. Iron monsters that matched the dinosaurs size and power. These logbooks are an account of their struggle for survival, when man and heavy construction machines are pitted against the most powerful and voracious dinosaurs ever to walk the face of the earth. Each logbook is taken from the four crew team leaders, depicting their eight months on the island. Eight months that were intended to be typical construction duties which included clearing, building roads and pads.After a short time, the crew came to the horrifying realization that they were in a prehistoric era, the Cretaceous period to be exact, and no communication with the outside world was possible.....as the outside world did not exist, yet! These logbooks tell of their battles, struggles, and triumphs on the island and must be read to be believed. The only way to fight fire with fire was for the teams to use their iron mechanized monsters against the dinosaurs in combat. It is truly an amazing adventure for all ages. |
