What This Document Is
This is a lab assignment for GY 112L, Earth History Lab, at the University of South Alabama, specifically focusing on Mesozoic fossils and rock suites. It represents the second installment in a two-part series exploring the geological period known as the Mesozoic Era – often referred to as the “Age of Reptiles.” The assignment is designed to be completed using physical specimens and requires students to apply their understanding of paleontological identification and geological principles. It builds upon concepts introduced in previous labs and prepares students for more advanced topics.
Why This Document Matters
This assignment is crucial for students enrolled in Earth History Lab who are seeking to solidify their understanding of Mesozoic life and the geological context in which it thrived. It’s particularly beneficial for those who learn best through hands-on examination of fossils and rocks. Successfully completing this lab will enhance your skills in fossil identification, stratigraphic interpretation, and understanding depositional environments. It’s best utilized *after* reviewing the background materials provided for the lab and during dedicated lab time with the provided specimens.
Common Limitations or Challenges
This assignment does not provide a comprehensive overview of all Mesozoic fossils or rock formations. It focuses on a specific selection of specimens available in the lab. It also assumes a foundational understanding of geological terminology and basic paleontological principles. The assignment requires access to the physical specimens themselves – this document alone will not allow you to complete the tasks. It does not include completed examples or answers to the questions posed.
What This Document Provides
* A series of specimen identifications and analyses relating to Mesozoic and near-Mesozoic fossils.
* Exercises focused on echinoderms (including crinoids, echinoids, and blastoids) and cephalopods (including ammonites and belemnites).
* Questions designed to assess understanding of fossil characteristics, classification, and paleoecological interpretations.
* A drawing component to reinforce observational skills.
* An exploration of Mesozoic-aged rock formations found within Alabama, focusing on sedimentary characteristics.
* Opportunities for bonus credit through additional drawing exercises.
