The primary decorative flooring tile in the Southpark Mall in Charlotte, North Carolina, is fossiliferous limestone that contains Jurassic ammonoids and belemnoids. Visible in these tiles are more than 500 ammonoids, many of which have been cross sectioned equatorially perpendicular to the plane of coiling. Upper-level undergraduate students from…

Discusses fossilization as a topic involving chemistry, geology, and biology. Describes the processes of silicification and pyritization. (MLH)

Describes a model that illustrates the operation of principles of adaptive radiation. The model used is constructed of materials that can be easily obtained. Suggestions for use are provided. (PS)

Describes an exercise whereby a biology class used a stairway to illustrate how fossiliferous rock strata were deposited, the oldest on the bottom and most recent at the top. Each step represents a dated boundary between adjacent geological ages, and each riser is labeled as a geological unit. Geological time is compressed to 365 days. Offers…
