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.

Like the pyramids of Giza and Stonehenge  Before addressing this point, I'd like to address the post about Kansas being flat. Land on Earth is not all at the same height. That's why it's not a perfect sphere. Look at a basketball, the height of the ball is equal at any two points. But, with Earth, certain land formations are taller than others. So imagine a basketball, but where certain parts are higher than others. That's why Kansas is flat, and that's why Everest is miles higher than the ground you're standing on.  Now, as far as ancient peoples, they did make the pyramids and Stonehenge. But, that doesn't make them experts in astronomy. The Egyptians believed that the Universe was rectangular, not flat. They also thought that Egypt was at the center of all existence. So, should we believe them?
