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.

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).
