RESUMO
A tubular bone bead dating to ~ 12,940 BP was recovered from a hearth-centered activity area at the La Prele Mammoth site in Converse County, Wyoming, USA. This is the oldest known bead from the Western Hemisphere. To determine the taxonomic origin of the bead, we extracted collagen for zooarchaeology by mass spectrometry (ZooMS). We also used micro-CT scanning for morphological analysis to determine likely skeletal elements used for its production. We conclude that the bead was made from a metapodial or proximal phalanx of a hare (Lepus sp.). This find represents the first secure evidence for the use of hares during the Clovis period. While the use of hare bone for the manufacture of beads was a common practice in western North America during the Holocene, its origins can now be traced back to at least the terminal Pleistocene.

Job placement trends in higher education at US institutions are bleak. Within anthropology and other social science disciplines this problem appears to be particularly pronounced. Recent studies focusing on placement in Anthropology using market share analysis have suggested that specific doctoral programs offer a greater chance of placing their graduates in faculty positions. Here we expand on that work, looking beyond market share to the number of graduates placed in positions relative to the total number of program graduates. Our results suggest that while large programs do indeed command the majority of tenure track placements by market share, much of this may be a product of the high numbers of graduates from these programs. Smaller programs can be proportionally as successful at placing their students in tenure track positions. The majority of PhDs in anthropology should anticipate gaining employment outside of a tenure track position. Training students for positions in private industry, government, and other non-faculty opportunities is essential.
