A Jack's Reef Horizon Settlement Cluster in the Central Scioto Valley

In 1992, Mark Seeman proposed the existence of a Jack's Reef horizon in Ohio. Little professional research has been undertaken on domestic sites since then though. The Jack's Reef horizon subsumes the Intrusive Mound complex. Archaeological excavations for the Rockies Express-East gas pipeline project identified three sites in the central Scioto valley that provide evidence of Jack's Reef horizon occupations in floodplain and upland settings flanking the river valley. Radiocarbon dates confirm habitation associated with this late Late Woodland culture from cal A.D. 630–1000. Excavation and geophysical data reviewed in this article indicate intensive habitation of large base camps and small-scale residential bases, with secondary refuse disposal, distinctive ceramics, a curated bifacial lithic technology, and an expedient flake-tool technology.     

The Western River Steamboat Heroine, 1832–1838, Oklahoma,USA: construction

This paper describes the design and construction of the side‐wheel steamer Heroine, a representative of the ‘western river steamboat’ type and the earliest example of its kind to undergo archaeological study. Heroine was built at New Albany, Indiana, in 1832 and sunk on the Red River between Oklahoma and Texas in 1838. The extensive remains of the lower hull show assembly practices in use during the developmental era of Mississippi River steamboats. The wreck also reveals a heretofore‐unknown technique for longitudinally strengthening these long, narrow, and very lightly built hulls.     

The prevalence of,and the relationship between some spinal diseases in a human skeletal population from London

The prevalence of osteoarthritis, osteophytosis, intervertebral disc disease and diffuse idiopathic skeletal hyperostosis (DISH) was determined in a group of skeletons excavated from the crypt of Christ Church, Spitalfields. Age-specific prevalence rates were calculated from the group of skeletons for which age at death was known from intact coffin plates. Osteoarthritis of the facet joints occurred most frequently in the cervical and upper thoracic regions and was also common in the lower lumbar spine. The disease was more frequently bilateral in the lumbar spine than in upper regions. Osteophytes were common in the thoracic and lumbar spines, whereas intervertebral disc disease was confined almost completely to the cervical region. Diffuse idiopathic skeletal hyperostosis seemed to be underrepresented in this group, but was more common in males than in females. Age correlated significantly with all the conditions except DISH. Multiple regression analysis was carried out using each of the conditions as the dependent variable in turn. Age accounted for more of the variance than any of the other conditions added as independent variables.
