2005 Field Season

Goals of Grant

Early work on fossil decapod crustaceans in Romania has suggested that rocks in the region contain early brachyurans (crabs) and anomurans that are key in understanding the evolution of the Decapoda. In addition, Cretaceous and Tertiary deposits in Romania are anecdotally known to contain fossil decapods but these have not been systematically studied. With two students, in the summers of 2004 and 2005 we visited museums and field localities in Romania to restudy existing collections and collect new material.

Romanian colleagues visited KSU and the United States National Museum, Washington, DC, in the fall of 2004 to supplement their work on the paleoecology of Jurassic and Cretaceous rocks of Romania.  While in the US, our Romanian colleagues Dr. Iuliana Lazar and Victor Barbu , both of the University of Bucharest, also attended the GSA Annual Meeting in Denver, Colorado, and also conducted research at the University of Dayton in Ohio with Dr. Michael Sandy.
Field work in the summer of 2005 included work in sites in Dobrogea, in eastern Romania, in Jurassic rocks containing both sponge-algal and coral reefs.  Work also included collecting in Jurassic rocks in the Bucegi Mountain area near Sinaia and Braşov in central Romania.  Numerous fossiliferous localities, previously unknown to contain crabs, were excavated.
