Evaluation of Sources
To start with my evaluations, I have chosen an encyclopedia article from www.encyclopedia.com. I searched the site for information about the article and found all the information I needed quickly and easily. The article actually comes from The Columbia Encyclopedia, Sixth Edition. The encyclopedia was copyrighted in 2008, which for my topic, fits the timeliness. I did not find the name of the author, but since it is in a recognized encyclopedia, I can find that information. There also were no citations, but there were many links to related articles. Overall this source is reliable and suitable for my paper.
My second evaluation is on the book The evolution and extinction of the dinosaurs by Professor David Fastovsky, Cambridge [U.K.]; New York: Cambridge University Press, 2005. He is a professor at University of Rhode Island in Geosciences. He has earned a PhD in Geology and has worked at many fossil digs. He used many sources that are all cited in the book. Again the timeliness of the book is okay for my topic and the suitability is great. He has written in many journals and is considered an authority on this subject matter. I would consider this an excellent source of information.
For my periodical article, I have chosen to use an article titled Mass extinctions and macroevolution from the journal Paleobiology. The article was written by David Jablonski who is a professor at University of Chicago. The article was published in June of 2005. The author is writing in a scientific journal and is, therefore, writing to his peers. The article was peer reviewed and cites sources for his information. The timeliness is still okay for my topic and the suitability is good for my research. Overall this is an okay source but I will continue to look for better articles.
For my website, there was one site that every search engine refers to. It is called DinoBuzz and is written by the University of California Museum of Paleontology. There are many links to all subjects related to dinosaurs. The authors of the site last updated in 2005 but it is still within the right time frame for my subject. All sources are cited on each article. The site is not as easy to navigate as some that I have looked at, but the information is suitable for my paper. DinoBuzz is a good source for basic information.
Quotation, Paraphrase and Summary
"But before we dive into the complex issue of the K-T extinction, we need essential background information to understand the basics of the controversy. The "great dying," as it is sometimes called, is an example of a mass extinction: an episode in evolutionary history where more than 50% of all known species living at that time went extinct in a short period of time (less than 2 million years or so)." www.ucmp.berkeley.edu/diapsids/extinction.html
Research into the extinction of the dinosaurs begins with a definition. We define a mass extinction as "an episode in evolutionary history where more than 50% of all known species living at that time went extinct in a short period of time (less than 2 million years or so)." With that definition in mind we will now delve into the extinction of the dinosaurs approximately 65 million years ago.
Before we can discuss the extinction of the dinosaurs we must define what constitutes a mass extinction. It is when most of the species on Earth died off over a period of time. This is the beginning of the controversy surrounding what actually caused the extinction.
As we begin our research of what caused the dinosaurs to die, we have to first decide what entails mass extinction. Mass extinction is a period of time that sees the majority of the species of life on the planet disappear over a period of about 2 million years.
