The Cretaceous Period In the Cretaceous Period started when the Jurassic period ended‚ which was exactly 144 million years ago and was also longer than any other period‚ reaching to approximately 65 million years. The Cretaceous period also marks the end of the Dinosaurs‚ who were destroyed by the meteorite that struck the earth 65 million years ago. In the Cretaceous Period there was a newly discovered bird or glider called‚ The Microraptor Gui or also known as The Dinosaur with Four Wings‚

Tyrannosaurus Rex was the dominant predator in the late Cretaceous period. The Tyrannosaurus Rex‚ or T-Rex for short‚ lived about 85 million to 65 million years ago. T-Rex often resided in moist‚ humid‚ semi-tropical areas‚ usually near rivers or forested swamps. T-Rex fossils have been found in North America and Mongolia. The T-Rex was a large‚ dangerous predator that walked on two powerful legs. It had tiny arms with two fingers each. Their feet resembled birds and were fully equipped with gargantuan

The Cretaceous Period and the Aftermath Imagine a great‚ thickly muscled dinosaur. Got it? See those serrated teeth? And the great yellow eye that is pondering whether you are food or foe? Now‚ imagine something that can kill this beast and all of its kind. This “something” is called the Cretaceous Tertiary Extinction event‚ and it occurred 65.5 million years ago‚ and killed all the dinosaurs‚ and affected the process of evolution forever afterward.

forward for the mass extinctions at the end of the Permian and Cretaceous (KT) Periods. A mass extinction is an event in which at least 25-75% of species in the global environment are eradicated in a short period of time. Where as a regional extinction event is when the extinction is confined to a specific zone. Five mass extinctions have occurred throughout time‚ two of the most well known of these are the Permian and Cretaceous extinction events. There are several hypotheses that are used

ABSTRACT Several mass extinctions have occurred during the Earth ’s history. The Cretaceous Tertiary Boundary (K-T) Extinction caused the loss of at least three-quarters of all species known at that time including the dinosaurs. The cause of this mass extinction is a controversial subject among scientists but the fossil evidence of it ’s occurrence is abundant. INTRODUCTION The K-T Extinction occurred 65 million years ago. Many species perished in that extinction. Today evidence for this extinction

During Jurassic Period the Pangaea started to break up into smaller units called Laurasia and Gondwanaland. In late Cretaceous period‚ the continents were further separated and transformed as present day continents (William Lowrie‚ 2007).

Fossil data from the mid to Upper Cretaceous period predicts the sequence of rock strata in Big Bend National Park to be from bottom to top: limestone‚ shale and clay‚ limestone again‚ and sandstone and clay.

This was during the Triassic period approximately 230 million years ago and the dominant terrestrial vertebrates for 135 million years from the beginning of the Jurassic and till the end of the cretaceous era. Jurassic means 201 years ago and cretaceous means 66 million years ago. The word dinosaurs means terrible lizard from the Greek language though they are not lizards. Instead they represent a separate group of reptiles which did not exhibit traditionally seen as reptilian
