Do you know T-Rex?

T-Rex - the most recognizable dinosaur!

When people asked about dinosaurs, T-Rex will always come to mind. Why?
Maybe because of its ferociousness, maybe because of its size, maybe because of its weird features (big head, large legs, tiny hands)...

T-Rex full name is Tyrannosaurus rex, which means 'tyrant lizard king'. How much do you know about T-Rex? And do you really think scientist know much either? There are no living dinosaurs today (at least not that I know of...do you?).

What we see in the movies regarding the dinosaurs are mostly based on theories, and these theories are mostly based on evidences gathered by scientist such as from fossils.

Here are some facts about T-Rex that most scientist believe...

• It is thought to lived in what is today western North America
• It lived during the Late Cretaceous Period (or in layman's term 68 to 66 million year ago)
• It is about 12 meters long, 4 meters tall, and weight up to more than 6 metric tons (very BIG!)
• It is considered to be the largest known land predator

Some questions that remains a debate among scientists regarding dinosaurs...

• Is it a predator or a scavenger, or both?
• It is warm blooded or cold blooded?
• Does it has scales like crocodiles, or feathers like birds?
• Is there a female and a male dinosaur?
• Is it's posture 'erect' or is it 'parallel to the ground'?
• How fast can it move? This can also lead to some answers regarding its predator vs scavenger behavior..
• Is it an 'intelligent' creature?
• Do T-Rex move in pack like wolves or do they hunt alone?
• Do they practice cannibalism?

To answer these questions scientist have to investigate their fossil remains and try to conclude on their body structure and behavior.

Some myth regarding T-Rex...

T-Rex and humans lived or have coexisted together...probably because in some 'stone age' movies, we can see human devoured by dinosaurs.
Not true since the last dinosaurs lived about 66 million years ago, long before human existence.

T-Rex lived during the Jurassic Era...probably because of Jurassic Park the movie
Not true since T-Rex lived between 68-66 million years ago which is in the Cretaceous Period, and the Jurassic Period is actually somewhere between 205-138 million years ago.

If you want to learn more about dinosaurs, be sure to check out documentaries on TV regarding dinosaurs. There are plenty of them especially on National Geographic Channel
