10 Amazing Facts about Dinosaurs

We're all familiar with dinosaurs from movies such as Jurassic Park and King Kong, but how much do you really know about dinosaurs? Here are 10 facts about dinosaurs which you can amaze your friends and family with:

1. Dinosaurs first appeared during the Triassic period (248 to 213 million years ago), and were the dominant land animals through the entire Jurassic period, and to the end of the Cretaceous period (65 million years ago).

2. We know about dinosaurs because fossils have been found. The fossils, which are generally found in sedimentary rocks, including fossilized body parts (bones, teeth, skin, claws, etc.), as well as trace fossils ("ichnofossils") which show how the animals lived, which include footprints, burrows, nests, toothmarks, dung, etc.

3. The earth's continents slowly move through a process known as "plate tectonics". When dinosaurs first appeared during the Triassic period, all the earth's continents were joined together in one super-continent known as "Pangea".

4. All the familiar types of dinosaurs, died off at the end of the Cretaceous period. There are many different theories why this may have happened, but today the most popular theory is that an asteriod hit the earth, blocking out the sunlight so that there was not enough food available. Evidence for this theory is a layer of iridium, which is believed to have come from the asteroid, has been found around the world, and a possible impact site found in southern Mexico.

5. The smallest known dinosaur is Compsognathus, which lived in Europe during the late Jurassic, and was about the size of a chicken. Compsognathus is believed to have eaten insects, lizards and other small animals.

6. There are quite a few candidates for the largest dinosaur, as there are several types of dinosaur that were over 100 feet (30 metres) long. The largest was certainly some kind of sauropod (a four-legged plant-eating dinosaur with a long neck) that lived during the late Jurassic or early Cretaceous period.

7. The word "dinosaur" was coined by Sir Richard Owen, who also founded the Natural History Museum in London, England. "Dinosaur" means terrible lizard, and is based on the Greek words "deinos" (terrible) and "sauros" (lizard).

8. People have been finding dinosaur fossils for hundreds of years, but didn't know what they were until quite recently. The first time that a dinosaur was scientifically described was in 1824, by William Buckland.

9. At the same time that dinosaurs dominated the land, there were many aquatic reptiles that dominated the seas, although these were not dinosaurs. These aquatic reptiles included plesiosaurs, nothosaurs, mosasaurs and ichythosaurs.

10. Although birds seem to have evolved from dinosaurs, no non-avian flying dinosaurs are known. However, at the time of dinosaurs there were many flying reptiles, known as pterosaurs.

Getting Rich is an Exact Science

This is the second in a series of articles based on the teachings found in the success classic "The Science of Getting Rich", written in 1910 by Wallace D. Wattles. This book-now in the public domain--is essential reading for anyone who wants to become wealthy.

In the second chapter of "The Science of Getting Rich", Mr. Wattles explains that getting rich is a science; in fact, it's an exact science, like mathematics. That is, there's a series of principles or laws that govern the process of acquiring wealth, and once these are learned and systematically applied by anyone, that person will get rich.

Mr. Wattles refers to the systematic application of the principles or laws of becoming rich as "doing things in a certain way". He adds that once a person begins to think and act in "a certain way", that person will become rich. The "certain way" in which to think and act is fully explained in later chapters of the book.

The first law Mr. Wattles cites is the Law of Cause and Effect, which states that like causes always produce like effects. If you swing your golf club in the same manner as a professional golf player, you will get the same results as he does, regardless of who you are. To quote "The Science of Getting Rich":

"If getting rich is the result of doing things in a certain way, and if like causes always produce like effects, then any man or woman who can do things in that way can become rich, and the whole matter is brought within the domain of exact science."

People tend to think that the following are the causes of getting rich:

The environment in which you're currently working or have set up your business. That is, the neighborhood, town, city, state, or country in which you currently work.

How much talent you have or how smart you are.

Choosing a particular business or profession.

Doing things others fail to do.

Having easy access to capital.

However, Mr. Wattles explains one by one why these factors are not the causes of achieving wealth. Getting rich is not a matter of environment; there are countless examples of people working in the same business and in the same neighborhood, but one fails and the other succeeds.

If the environment were the cause of getting rich, everyone in the same state would be rich, while those in another state would all be poor. Although it is true that some environments or locations are more favorable than others, the environment is not the cause of getting rich.

Also, talent is not the cause of getting rich, for there are many talented people who are not wealthy, and there are many people with little talent who are very rich. There are many intelligent people, often with high education, that fail at achieving financial success, while there are many college drop outs who become millionaires.

Additionally, people get rich and people fail in every business and in every profession. It is true that you will do better in a business that you like, and if you have some well developed talents you will do better in a business in which you can apply those talents, but getting wealthy is not determine by the business or profession you choose.

Getting rich is also not the result of doing things others fail to do, for two people in the same business can be carrying out the same activities, but one gets rich and the other files for bankruptcy. There are a lot of hard working people whose lives are filled with struggle and who never manage to accumulate wealth.

In addition, a lack of capital will not prevent you from getting rich. You can slowly begin to get access to capital and, as you progress, the access to capital will become easier and faster.

For the reasons set forth above, Mr. Wattles concludes that the aforementioned factors cannot be the cause of getting rich. So, if getting rich is not a result of the factors discussed above, what does getting rich depend on?

Mr. Wattles explains that in order to become rich you have to do things in "a certain way", regardless of where you are, what business you're in, how much capital you have, or how talented you may be.

What you need in order to be able to do things in this "certain way" is:

Enough intelligence to read and understand "The Science of Getting Rich".

A willingness to interact with people to some degree.

Basic common sense; for example, don't start a salmon fishery where there are no salmons.

And, most importantly, begin to live in harmony with the laws governing the universe. These laws are explained in "The Science of Getting Rich".

Since like causes produce like effects, no matter who you are, where your business is located, or what your personal circumstances may be, if you act in accordance with the principles and laws that govern the process of acquiring wealth, you must get the results you're looking for. The cause is doing things "in a certain way", and money is the effect.

Mr. Wattles says to start where you are right now. Begin in your present business-or other situation-, and in your present location, to do things in a certain way which causes success. Begin right now, wherever you are.
