**What This Document Is**
This is a lab assignment for GY 112L, Earth History, at the University of South Alabama, specifically focusing on the Paleozoic Era. Assignment 7 is divided into two main parts: an exploration of key Paleozoic fossils and an exercise in stratigraphic interpretation. It requires both observational skills – through specimen drawing – and analytical thinking to understand geological relationships. The lab builds upon previous work with fossil identification and geological mapping techniques.
**Why This Document Matters**
This assignment is crucial for students enrolled in Earth History who are aiming to solidify their understanding of Paleozoic life and geological principles. It’s best utilized *during* a lab session, allowing for hands-on examination of specimens and application of learned concepts. Successfully completing this assignment will demonstrate competency in fossil identification, understanding ancient environments, and interpreting stratigraphic sequences – skills essential for any aspiring geologist or paleobiologist. It’s designed to reinforce lecture material and prepare you for more advanced topics in historical geology.
**Common Limitations or Challenges**
This assignment does not provide a comprehensive overview of the entire Paleozoic Era. It concentrates on a select group of fossils and a specific stratigraphic scenario. It also assumes prior knowledge of basic geological principles, fossil identification techniques, and stratigraphic symbols. The assignment requires independent research to fully answer some questions, and the quality of your drawings will be assessed, demanding careful observation and artistic skill. Access to the actual specimens referenced in the lab is required to complete the assignment.
**What This Document Provides**
* A series of written questions prompting investigation into significant fossil discoveries and their implications.
* Detailed instructions for observing and analyzing specimens from the Phylum Arthropoda and Phylum Hemicordata.
* Guidance on creating scientifically accurate sketches of geological specimens, including considerations for scale and shading.
* A real-world geological scenario involving a rock suite from the Colorado Rocky Mountains.
* Exercises in identifying rock types, interpreting depositional environments, and constructing stratigraphic profiles.
* A challenge to identify a specific type of unconformity within a given geological sequence.
