These shells are composed largely of aragonite CaCO3 and potentially could be used for radiocarbon dating, but they must meet two criteria before their 14C ages can be considered to be reliable: To evaluate the first criterion, we conducted a comprehensive examination of the 14C content of the most common small terrestrial gastropods in North America, including AMS measurements of modern shell material individual shells from 46 different species. The modern gastropods that we analyzed were all collected from habitats on carbonate terrain and, therefore, the data presented here represent worst-case scenarios. For the second criterion, we report a case study from the American Midwest in which we analyzed fossil shells of small terrestrial gastropods 7 taxa; 18 AMS measurements; individual shells recovered from late-Pleistocene sediments. The fossil shells yielded 14C ages that were statistically indistinguishable from 14C ages of well-preserved plant macrofossils from the same stratum. Although just one site, these results suggest that small terrestrial gastropod shells may behave as closed systems with respect to carbon over geologic timescales. More work on this subject is needed, but if our case study site is representative of other sites, then fossil shells of some small terrestrial gastropods, including at least five common genera, Catinella, Columella, Discus, Gastrocopta, and Succinea, should yield reliable 14C ages, regardless of the local geologic substrate.

On Santa Rosa Island, one of the Channel Islands just 65 kilometers from Santa Barbara, nearly 20 sites have been found that reveal signs of prehistoric human activity, from massive middens of abalone shells to distinctive stone points and tool-making debris. Torben Rick of the Smithsonian Institution, who led the survey that uncovered the sites. The discovery adds hefty new data to the already mounting evidence that maritime Paleoindians — also known as Paleocoastal peoples — lived along the California coast at the end of the last ice age.

Modern members of the Chumash, who have inhabited the Channel Islands for thousands of years, re-create a crossing to the islands in a tomol canoe. Uncovering hard evidence of this coastal migration has proved challenging, however, because the shorelines that Paleocoastal people would have followed have long since been submerged by rising seas. It was while studying some of these sites on San Miguel Island — another of the Channel Islands — that Rick and his colleagues made a key observation: They noted that Paleocoastal settlements tended to have certain traits in common that made them more suitable than sites right on the water.

Optimal locations were also near sources of useful raw materials, like chert for making tools, as well as fresh water and rockshelters or caves for refuge. Distinctive crescent-shaped stone tools, like this from neighboring San Miguel Island, are among the Paleocoastal artifacts that have been identified. Upon surveying the area, the team found 19 sites that showed signs of human occupation, mostly middens, or piles of detritus left over from generations of tool making and food preparation.

Although they were essentially prehistoric trash piles, these middens offered a wealth of useful archaeological clues, some deposits covering more than 75, square meters over 18 acres. Nine of the these sites contained the distinctive Channel Island barbed stone points that are indicative of Paleocoastal culture from the late Ice Age, Rick reported, and several also contained caches of shells from red abalone — a staple food of Paleocoastal Indians.

Buy The federal Bureau of Land Management BLM , which has custody of the collection, spent the last five years simply creating an inventory of the items. Before they were seized, these objects had been held in secret, stashed in closets and under beds or locked away in basement museums. Recently the BLM gave Smithsonian an exclusive first look at the objects it has cataloged.

Beyond the sheer size of the collection is its range: Some of the objects, such as projectile points and metates, or grinding stones, date to about 6, B. Among the more than 2, intact ceramic vessels, many appear to be from the Ancestral Puebloan people, or Anasazi, who lived on the Colorado Plateau for some ten centuries before they mysteriously departed around A.
