Early Zea Cultivation in Honduras
Late Holocene Fire and Agriculture in the Copan Valley, Honduras
Pollen and charcoal analysis of a 5.3-m sediment core from Aguada Petapilla, a peat bog, provides evidence of late Holocene vegetation and fire history in the Copan Valley, Honduras. Low concentration and preservation problems characterized the pollen flora, but there are taxa present indicative of major agricultural trends, including Zea mays. Microscopic charcoal fragments are well represented and record continued burning in the region since th…
Human-Environment Interactions in a Tropical Watershed
Questions of past human-environment interactions are best addressed by a research agenda that recovers complementary archaeological and paleoenvironmental data. We have used such an approach in our investigations at Laguna Tamarindito, a small lake located in the SW part of the Peten rainforest of Guatemala. In 1991, a sediment core was taken from the lake as part of a larger program of research examining the history of human-environment interact…

Palynological contributions to the chronology and stratigraphy of the Hartford basin in Connecticut and Massachusetts
Recent discoveries of palynoflorules at numerous localities in the Newark Group basins of the eastern United States provide new evidence for correlation of deposits in these basins. Floras from the Shuttle Meadow and Portland Formations of the Newark Group rocks in the Hartford Basin of Connecticut and Massachusetts indicate that the Triassic‐Jurassic boundary is located within the rocks of this basin: a shift of Corollina from more than 90% C. m…
The challenge of abundance in palynomorphs
A palynological study of shales and “coals” of a Devonian‐Mississippian transition zone, central Pennsylvania
A section of Catskill Formation (Devonian) carbonaceous shales including pockets and small beds of pyritic, vitrinitic, high‐volatile A bituminous “coal” ( >40 percent ash) was uncovered during construction of Interstate Highway 80 in Centre County, Pennsylvania. The carbonaceous sediments are up‐section from reddish mudstone and gray sandy siltstone containing poorly preserved plant fossils, and the whole sequence is presumably deltaic. Stratigr…
Palynology of the Dakota sandstone (middle cretaceous) near Bryce canyon national park, Southern Utah
The Dakota Sandstone, the oldest formation of Cretaceous age in south‐central Utah, has long been a problem for the paleontologist and paleoecologist. In this area it was deposited on the western fringe of a broad, shallow, fluctuating sea, which extended from the Gulf of Mexico to the Arctic Ocean. Probably because of the salinity and poor circulation in the ancient sea, few megafossils occur in the formation. Little hope was held that the paleo…
A case of marginal palynology
The Franciscan rocks on which much of greater San Francisco, California, is built, have been the subject of geologic investigation and speculation for a century. Recent investigations by Hsü and colleagues have indicated that type Franciscan rocks are mélanges, consisting of allochthonous blocks of diverse sedimentary units mixed by complex tectonic activity. Establishment of the original stratigraphic positions of the blocks has been hampered bo…
Palynology, petrology, and depositional environments of some early tertiary lignites in Texas
Predominantly nonmarine early Tertiary sediments of the Wilcox Group in Texas include numerous local lignite deposits. Recent subsurface mapping has defined several interrelated depositional systems representing six sedimentary environments, in outcropping and subsurface Wilcox in Texas. Lignite occurs in three of the environments so defined; these are (1) fluvial, (2) deltaic, and (3) lagoonal. Plant microfossils and coal macerals from the Wilco…
Preliminary report on triassic spores and pollen of the Dockum group, Texas panhandle
A clay deposit in the Tecovas formation, an Upper Triassic unit in the Texas panhandle, has yielded abundant pollen of gymnospermous affinity. Most abundant is the bisaccate form Vitreisporites (Caytonipollenites). The remainder of the assemblage is comprised mostly of other bisaccate genera. In contrast to most other Triassic assemblages, striate grains have not been found. Another anomaly exists in that spores and asaccate grains constitute a r…
