Foraminiferal Genera and Their Classification
Studies with the foraminiferida have often been hindered by widely scattered, inaccessible sources. This two-volume reference (text in one volume, plates in the other) examines 3,568 of the world's generic taxa, representing all geologic ages. Covering twice the number of genera as any other available reference, it is by far the most complete source on the foraminiferida.
Ecology of Foraminifera from San Antonio Bay and Environs, Southwest Texas
Foraminifera populations have been analyzed from approximately 320 equal-size samples of surface sediment from a nearshore area on the southwest coast of Texas. The Foraminifera populations are grouped into four biofacies, as follows: open gulf, hay, marsh, arid river biofacies, Two subfaeies are distinguished. a beach subfacies and an upper San Antonio Bay 'subfaeies.' Mixed faunas occur in the lower bays, particularly near passes. Two principal factors causing the biofacies distribution in this area are believed to be the presence of barrier islands with narrow passes and variations in runoff into the bays. During times of low runoff oceanic water invades the bays, evaporates, and relatively high salinities result. Many of the open gulf species invade with the oceanic water masses at times of low runoff, and appear to become established within the bays.
