Title:
Intraspecies Size and Frequency Distribution of Platystropia clarksvillensis Vertically Within the Liberty Formation
Proposal:
Platystropia sp. are quite common within the in Platystropia sp. size and abundance occur vertically within the formation. Implications of these findings could demonstrate that an increase in size and abundance could have resulted from more favorable living conditions. More favorable living conditions could have included climatic differences, reduction in interspecies competition, more abundant food supply or a combination of two or more.
We will be sampling the Indiana St. Route 1 road cut near Brookville, Indiana. Upon approximating the surface area of the Liberty formation exposed at the site, we will employ the use of a belt-transect tecnique to demonstrate our hypothesis. This tecnique involves dividing the face of the formation into a specified number of transects and then sampling at alternating intervals with a set sampling box. All loose fossils and attatched slabs will be collected for analysis. Loose slabs will be omitted from the study because they have most likely fallen from a higher elevation within the formation. As previously stated, we will be focusing on Platystrophia clarksvillensis. For each sample, the frequency and mean size of the species will be recorded. Appropriate statistical analysis will then show correlations and significance vertically within the formation.
