| Summary: | A total of 103 genera and 157 species of terrestrial pollen, Analysis of the dinoflagellate taxa reveals that the Analysis of the dinoflagellates reveals a gradient between and at least 36 genera and 52 species of dinoflagellates were and may indicate the possibility that the environment of assemblages through time, although diversity was similar between most samples. both groups of taxa. Analysis of the terrestrial Burleson County, Texas. Both terrestrial and marine taxa confirm a Middle Eocene (Bartonian) age for the section. deposition was on the limit of the salinity tolerances for during deposition of this section was subtropical to environment of deposition of the core is open marine, shallow intermixed with open marine taxa may be a result of high no relationship to lithology was found. Principal Component of the terrestrial and marine assemblages illustrates a of the terrestrial pollen taxa indicate that the climate open marine environment. Multivariate statistical analysis palynomorphs reveals slight changes in the terrestrial recovered from a core taken from the Stone City section in shelf. The presence of brackish and freshwater taxa stratigraphic relationship between taxa in samples, although terrigenous input into the open marine environment. Analysis the brackish water and the open marine taxa in the section, the core may identify a transport mechanism responsible for the introduction of the brackish and freshwater taxa into the tropical; furthermore, the abundance of terrestrial taxa in |
