A Strange Fish Indeed: The Discovery of a Living Fossil

Through a series of fictionalized diary entries, this case recounts the 1939 discovery by Marjorie Courtenay-Latimer (and identification by J.L.B. Smith) of a living coelacanth, a fish believed to be extinct for over 70 million years. Developed for use in a freshman biology course as an introduction to the nature and methods of scientific inquiry, the case could also be modified for use in a number of upper-level biology courses such as ichthyology, evolutionary biology, and conservation ecology.

The Coelacanth: An Odd Fish 

This "clicker case" is a redesign of a case, also in our collection, by Robert H. Grant titled "A Strange Fish Indeed: The 'Discovery' of a Living Fossil." The case follows the story of Marjorie Courtenay-Latimer and her discovery of the coelacanth, a fish of considerable evolutionary interest. It uses the story as a springboard to explore evolutionary concepts and the scientific method. It has been reformatted to use student personal response systems (“clickers”) and a PowerPoint presentation (~4.2MB), and further emphasizes the role of Ms. Courtenay-Latimer. The case is designed for large introductory biology courses.
