Dinosaur - In the Footsteps of Dinos

Dinosaurs - Colorful Creatures?

The word dinosaur might make you picture large green beasts, but that's just the work of artists and your imagination. The truth is that nobody really knows what color dinosaurs were. These guys have been buried for over 200,000 years and you can't tell what color they were from fossils. Palaeontologists (scientist who study dinosaurs) believe dinosaurs were probably earth-tone colors - green, gray, brown - just like reptiles today, so they would blend into their environment.

Dinosaurs - The Name Game

Most dinosaur names aren't as easy to say as T-Rex. Try saying these names out loud: Procompsognathus, Tuojiangosaurus, Archaeopteryx. Dino names usually combine Latin or Greek words, which often describe the dinosaur. Triceratops means 'three-horned face'. Other times they are named after the place they were discovered like Arctosaurus found near the Arctic Circle. Yaleosaurus was named for Yale University. Some dinosaurs are even named for people. Palaeontologist Orthneil C. Marsh had Marshosaurus named after him. About 700 species have been named. That's a tough list to memorize.

Dinosaurs - Beginning to End

The years dinos roamed Earth are divided into three periods, which are called the Mesozoic Era.

  • Triassic Period (225 to 193 million years ago) - During the Triassic Period, dinosaur ancestors were evolving. In the Late Triassic, the world saw the first true dinosaurs.
  • Jurassic Period (193 to 136 million years ago) - In the Jurassic Period, the number of dinosaurs grew.
  • Cretaceous Period (136 to 65 million years ago) - By the Cretaceous Period, many different types of dinosaurs had evolved.

Dinosaurs - Bon Voyage

Scientist know dinosaurs were no longer around 65 millions years ago. They can tell how old layers of rock are and no dinosaur bones have been found in rock less than 65 million years old. So how did they all die out? There are two main theories about this:

  • Gradualistic theories say the dinosaurs were in a slow decline and that gradual changes in the environment caused their extinction.
  • Catastrophic theories say the dinosaurs disappeared abruptly due to some world-wide catastrophe. Perhaps a giant meteor crashed into Earth, covering the world in dust and hiding the warmth from the Sun.

Dinosaur Fun Facts

Dear Diary,  (2-20-17) So today was crazy after arguing with the fact that i should write this in a real diary but then remembering that my handwriting is terrible.     Okay look, just call me crazy but I saved the new girl in our class. I hate new girls in school. I was one which means I hate myself a couple years ago. That's..actually surprisingly accurate. Not that I'm a bully or anything whatsoever, but she always is automaticlly popular declared by the populist of popular in out class, Victoria. Or Tori for a brief yet still so disgusting I can smell her name from here period. Okay, I think we might be becoming friends after I saved her. You might be thinking, Audrey, just tell us how you saved her! Shut up, okay! I'm getting to that. Anyways, as Victoria is officially awesome, (inflicted by the awesomeness)  she hangs out with another girl which makes Alexei all mad and the whole thing blows up until I'm in the middle. (face palm) And I did some magic talk and problem solved. NOT! Now she says that I'm her friend and I do something crazy for her. She likes a boy in our class, Eddie. He likes Alexei, Alexei likes him. And you guess what i did. MAGIC! Anyways, now she owes me two favors. And that'll be getting me out of my delehma  right now by giving me stomach medicine. Or nose medicine. Either sounds heavenly.

In my opinion, cutting is not a cry for attention. The person's emotional pain creates some kind of need to feel physical pain, even if this person is not aware of that while doing it. However, on the last couple of years, cutting started to get popular, making some people think that if they cut themselves they will get more attention, which, also in my opinion, is an act of "desperation" and an actual need for attention or friendly advises .   :nerd  :)
