Pollen Preservation

The recovery of pollen from archaeological sites in Eastern North A merica has not been as successful as it has been in the western part of the continent. The depositional environment of eastern archaeological sites is generally unfavorable for pollen preservation and archaeologists have failed to search out special situations in which pollen may be preserved. At the Rhoads site, a Proto-Historic Indian village in central Illinois, abundant pollen has been found associated with copper artifacts and deeply buried tree bark. Pollen was preserved around copper, apparently due to dissolved copper salts which act as a fungicide. Tree bark, an excellent collection surface for air-borne pollen, can yield abundant pollen when preserved. When the factors involved in pollen deposition and preservation are considered, the prospects for archaeological palynology in eastern North America should be greatly enhanced.

Ceratopsids (“horned dinosaurs”) are known from western North America and Asia, a distribution reflecting an inferred subaerial link between the two landmasses during the Late Cretaceous. However, this clade was previously unknown from eastern North America, presumably due to limited outcrop of the appropriate age and depositional environment as well as the separation of eastern and western North America by the Western Interior Seaway during much of the Late Cretaceous. A dentary tooth from the Owl Creek Formation (late Maastrichtian) of Union County, Mississippi, represents the first reported occurrence of Ceratopsidae from eastern North America. This tooth shows a combination of features typical of Ceratopsidae, including a double root and a prominent, blade-like carina. Based on the age of the fossil, we hypothesize that it is consistent with a dispersal of ceratopsids into eastern North America during the very latest Cretaceous, presumably after the two halves of North America were reunited following the retreat of the Western Interior Seaway.

Ceratopsids (“horned dinosaurs”) are known from numerous specimens in western North America and Asia, a distribution reflecting the inferred subaerial link between the two landmasses during the Late Cretaceous. However, this clade was previously unknown from eastern North America, presumably due to limited outcrop of the appropriate age and depositional environment as well as the separation of eastern and western North America by the Western Interior Seaway during much of the Late Cretaceous.

Haplotype Frequencies

Abstract In eastern North America, evidence for cryptic northern refugia could contribute to resolving Reid’s Paradox, the disparity between the rate of oak recolonization indicated by pollen deposition and the rate indicated by contemporary seed dispersal studies. Severe anthropogenic disturbance of oak-dominated forests throughout eastern North America followed by regeneration from isolated patches and deliberate planting in some regions could obscure the signal of discontinuity expected from small, cryptic refugia. In this study of northern red oak, Quercus rubra L., the dominant representative of Quercus section Lobatae in the eastern United States, we address the question of appropriate sample size for accurate detection of the biogeographical distribution of chloroplast haplotype diversity in Q. rubra. We examined chloroplast DNA (cpDNA) variation in all Q. rubra over 17 cm in diameter (310 trees) in three forest fragments with documented histories of minimal disturbance for the last 100-190 years. cpDNA polymorphisms in three intergenic regions revealed different haplotype frequencies between the two local fragments located within 1 km of each other and complete discontinuity for the predominant haplotype between these two sites and a site 207 km distant. Haplotypes displayed positive spatial autocorrelation over 10-40 meter distances. Sample sizes of 10 or fewer taken at 50 meter intervals along a linear transect yielded poor estimates of haplotype frequencies and did not accurately detect haplotype richness.

AbstractRemote sensing has revolutionized procedures for locating buried features at archaeological sites in eastern North America. However, the potential of instruments such as gradiometers to shape innovative research in ways that move beyond survey and testing is not always realized in practice. At the Mississippian site of Moundville, Alabama, we conducted a landscape-scale geophysical survey to serve as the guiding method of community settlement analysis. First, we mapped the distribution of magnetic anomalies across the site. Next, we defined the variability of anomalies and selected a sample for test excavations to correlate specific anomaly shapes and amplitudes with specific cultural features. Once confirmed as cultural features, we extrapolated sample results to identify unexcavated anomalies as specific building forms and other features with a higher degree of probability than would have been possible without confirmation by test excavation. Results include the identification and mapping of over 450 unexcavated probable buildings, nearly five times the number previously discovered in decades of traditional excavation. Because the buried probable buildings have different forms, sizes, distributions, and chronological spans, the interpreted gradiometer map is transformed through interpretation from a static palimpsest of anomalies to a picture of changing community settlement organization.

This volume’s case studies recognize the black bear (Ursus americanus) to be among the most socially consequent of species in Native Eastern North America, despite meager remains at many archaeological sites. Indeed, that sparseness offers valuable evidence for the social roles long played by bears. Ethnohistorical sources suggest bear population densities in some habitats were greater than seen today in Eastern North America. Most archaeological assemblages of bear skeletal remains have skull parts and foot bones but lack most other postcranial elements, often reflecting ritual off-site discard of post-cranial remains and feasting on head and feet. Differences in quantities of bear remains, their relative proportions to other mammals, and differing representations of various parts of the bear skeleton are sensitive indicators of a society’s relationship with black bears. We apply precepts of the new animism, or the ontological turn, to animate the zooarchaeology of bears in Eastern North America.

Among the various pre-maize indigenous crops of eastern North America, Cucurbita pepo gourd is the most enigmatic.C. pepogourd remains have been found on mid-Holocene (8000–4000 B.P.) archaeological sites as far north and east as Maine. Their presumably extremely bitter flesh would have made the fruits inedible. Two not mutually exclusive hypotheses for use of the fruit are currently being debated: (1) the nutritious seeds were processed to remove bitterness and consumed, and (2) dried fruits were used as fishnet floats and/or containers for general use. We report on a series of experiments that demonstrate the gourds function extremely well as fishnet floats. These results lend support to the second hypothesis, but do not conclusively prove they were used for this purpose.

New Evidence

Squash remains from three Late Archaic archaeological sites constitute the earliest evidence for cultigens in eastern North America. The new data indicate the tropical cultigen, squash, was introduced into the area prior to the domestication of native plant resources.
