Book Description
The Little Cove Point Member belongs to the St. Marys Formation in Maryland, which is part of the Miocene Chesapeake Group. The objective of the research is to reevaluate the Miocene mollusk systematics, paleoecology, and paleobiodiversity of the Little Cove Point Member. Two sets of mollusk fossils were provided by the Calvert Marine Museum that represent bulk, samples of studied materiel taken from one l cubic meter area, and grab samples, samples of studied material taken from one or more small area. One set of data was obtained from the Chesapeake Bay Benthic Monitoring Program that include Holocene Mollusca fauna of the bay. The bulk sample includes 35 genera, the grab sample include 20 genera while the modern sample have 21 described genera. Four species were recorded for the first time in the Little Cove Point Member in this collection, Chesapecten santamaria, Chesacardium laqueatum laqueatum, Lirophora parkeria, and Spisula subcuneata. The paleobiodiversity was measured using the Shannon index (H). Then richness, the number of different species represented in an ecological community and evenness (E), the measure of the relative abundances of species within a community, of the species was calculated. The similarity between the community of mollusks was tested using Sorensen's coefficient. The bulk sample has higher biodiversity index than the extant fauna, while the grab sample has a lower biodiversity than the bulk sample. Bulk sampling provides a better representation of biodiversity measurements than a grab sample.
