A number of economically important marine fishes inhabit the estuaries, in- cluding black drum, redfish (or red drum), seatrout, and sheepshead (Hoese and Moore 1977; Shew et al. 1981). These fish are tolerant of a wide range in salinity, and their bones and otoliths have been identified in archeological contexts from the barrier islands inland to brackish wa- ter deltaic areas. Also ranging throughout the estuaries are gar fish, the prehistoric exploitation of which is indicated by bones and scales at shoreline sites throughout the area. The wooded floodplains from stream mouths and farther inland are home to various economically useful animals, most notably white-tailed deer, as well as various smaller mammals and reptiles. Herds of antelope and bison roamed the inland prairies in the western part of southeast Texas in Late Prehistoric and Early Historic times. Patterns of Paleoenvironmental Change Recent research in southeast Texas and Fig. 6.1. Map of southeast Texas indicating major rivers and coastal bays and broad zones of nearby areas has highlighted two kinds of vegetation: 1, longleaf pine and mixed pine–hardwood forests; 2, oak savannas and grasslands; 3, coastal upland prairie; 4, coastal marsh–prairie zone (simplified from Diamond et al. 1987). fundamental, long-term environmental changes, both of which probably have significant implications for understanding ing.
