Ichnological zonation of a modern macro-tidal flat and comparison with Early Pennsylvanian intertidal paleoichnology
Extrapolation to trace fossil suites of intertidal deposits in the geologic record will aid interpretation of microenvironments and tidal ranges of these past depositional environments.
Paleocene echinoid faunas of the eastern United States
A comprehensive review of echinoid species from the Paleocene of the Gulf and Atlantic coastal plains of the US, including extensive new collections from the outcrop belt in southeastern US.
Flood vulnerability indices and emergency management planning in the Yazoo Basin, Mississippi
A method is developed in which indicators are used to categorize the vulnerability to catastrophic flooding by considering physical, social, economic, and environmental components of susceptibility.
