Description

Term Paper Detailed Guidelines

Overview:  Throughout the quarter you will gather information about a specific extinct species.  After conducting a literature review of the published scientific articles about this species, you will write a term paper including pictures and graphs.  

Topic: Choice of Dunkleosteus.

Required Sections: Your paper should have three distinct and labeled sections:

Species overview - the name of the species, a general overview of it's size, paleobiological details and a phylogenetic tree (Links to an external site.)showing it's relationship to other species. If available, include an artist rendering of what the species likely looked like as well as a reconstructed full fossil representation.

Fossil Finds - Discuss the first significant fossil find and naming of this species. Discuss at least two primary resource papers and display and explain the graphs and pictures from the research.  

Species significance - Explain why this species is significant (scientifically, not to you personally) and how research about this species has increased our understanding of geologic history.

How to read primary source paleontology articles First, it is important to find multiple primary source articles related to your topic. I recommend reviewing our class librarian video which discusses how to find and identify primary source articles: https://www.youtube.com/watch?v=ygkr1hV-Stc&feature=youtu.be Scientific Articles - Sections Many scientific articles, particularly if the paper has been published in the last 15 years will have the following sections: 1. Abstract (A short summary of article. This is very dense and filled with advanced vocabulary but will provide all the key information from the article.) 2. Introduction (This gives overview of topic and provides a background. Often it will include information about the species significance.) 3. Methods/Materials (Explains the study/experiment and sometimes materials used. For fossil finds this may include information about who originally found the fossil and how a paleontologist came to access the fossil.) 4. Results (findings of the study/experiment) 5. Discussion (what the findings mean and what else remains to be known) Paleontology Articles - Additional Sections Paleontology articles will follow this format but will often have additional headings. For your Term Paper, you will likely read the scientific paper about the discovery and naming of the first specimen of your species (also known as holotype). This article, particularly if the paper has been published in the last 15 years may have the following additional sections: ● Occurrence and geological setting (This will discuss where the fossil was found and the details known about the outcrop and how the skeleton (or portion of the skeleton) was found.) ● Systematic palaeontology (This will provide the details for the naming of the new species and include all the taxonomy (Links to an external site.) details.) ● Osteological description (This is a description of the skeleton (if animal) and how complete it is. Other sections may follow discussing the different sections of the skeleton if it is a more complete fossil. These are usually very detailed descriptions because they need to clarify why this is believed to be a new species.) ● Results of the phylogenetic analysis (A phylogenetic analysis is the process of measuring specific parts of a fossil to properly identify it or, in the case of a holotype, to make the case that it is a new species.) Hints and Tips for reading scientific articles Don't get overwhelmed by the descriptive adjectives. You probably won't understand every word since you are not a professional paleontologist but you can understand the main points which is exactly what you need for your Term Paper. Don't get bogged down in the detailed descriptions of the fossils. Instead focus on the main points and significance of the fossil finds - these can be found in the abstract, introduction and conclusion. Often quality secondary sources, such as National Geographic or Ars Science (Links to an external site.), will have articles discussing the primary source material of new fossil finds. These sources are a great help to understanding the significance of the fossil find. Zuul Crurivastator - article link and powerpoint Zuul crurivastator is the species we discussed in lecture. You are NOT responsible for any material from that lecture or article linked below. I hope this discussion will help you understand how to interpret the primary resource paleontology papers you will read for your term paper.

Powerpoint of in-class lecture: Zuul crurivastator.pptx What is a Primary Source? In the sciences, a Primary Source is the original publication of new research, data or theories by the person(s) who conducted the research or formulated the theory. Primary Sources are typically published in Scholarly Journals, accessible through library databases like Academic Search Premier (EBSCO). They are often characterized by standardized sections - you can remember them with the acronym AIMRAD. A - Abstract (short summary of article) I - Introduction (gives overview of topic) M - Methods/Materials (explains the study/experiment and sometimes materials used) R - Results (findings of the study/experiment) A - And D - Discussion (what the findings mean and what else remains to be known) They will also have a long list of References (the sources the authors used) at the end. Sometimes the sections might be combined, named differently, or unnamed, so if you aren't sure if what you have is a Primary Source email Haley or Ask a Librarian. https://www.youtube.com/watch?time_continue=2&v=ygkr1hV-Stc&feature=emb_logo Reference List Requirements and CSE Citations Provide a numbered list of all your source material at the end of your term paper. The list should be in CSE format (numbered in the order you cite within the paper). When quoting or paraphrasing another person's words or ideas (which is almost all of your paper), you must give credit to that person. You do this with an in-text citation. In the Citation-Sequence system used by CSE, the in text citation is a number, either in superscript or in parentheses. The notations go in numerical order and correspond to the numbered references given at the end of the paper. Our library has set up a CSE Citation-Sequence Citation Guide website (Links to an external site.) This website gives all the information you need to properly list the different types of source material. We also have a library resource guide (Links to an external site.) to help you find primary source material. While you should have some direct quotes, please limit these to less than 25% of your paper. Most of your text should be paraphrased, not direct quotes. Ideally, you will have many sentences in your own words but using scientific research and ideas. While a significant majority of your sentences will contain one or more citations, this does not mean you will not be exhibiting your own writing. Also, please assume I will check your paper for plagiarism and will read the wikipedia page of your species.

TERM PAPER
Section 1; Species Overview
The species to be discussed in this paper is Dunkleosteus terrelli, it is an extinct genus,
and large vertebrate existed in the late Devonian period.
The size is very large, an estimation was made said that the weight is about 665 kg, and
the length is about 4.6 meters (1). Dunkleosteus terrelli belonged to placoderms, which as a
diverse clade of early fishes (2). Dunkleosteus terrelli is now considered as one of Earth’s first
vertebrate predators (2). The discussed species and great white sharks have many similarities
(not only their niche), but also the similarities related to the way they function, both
Dunkleosteus terrelli and white sharks were known for the ability of swimming and the
estimation that they were continuous swimmers (2). Regarding Dunkleosteus terrelli's position in
the phylogenetic tree, Dunkleosteus terrelli is considered one of Earth’s first vertebrate apex
predators, and more complex swimming vertebrates had appeared after the extinction of
Dunkleosteus terrelli (2).
