Unusual incirrate octopods from the South Shetland Islands, Antarctica, including Bathypurpurata profunda, a newly discovered genus and species of deepwater pygmy octopod (Cephalopoda)

Among the many octopods collected during recent Antarctic trawling were several species that do not belong to the common Antarctic pareledonin fauna. Three species are either poorly known or new to science, so we describe their morphology and anatomy. A very small (23 mm dorsal mantle length, ML) mature female of a fragile, dark purple species without an ink sac has suckers in a single series and proportionally huge salivary glands. We consider it to be a new genus and species. A single Graneledone antarctica Voss is unusual because it is the largest reported specimen (104 mm ML) and the first mature female. Six “Bentheledone” from a single deep (3213 m) sample and another, mature male caught nearby over five years later, may be B. albida (Berry), until now known only from the holotype. They are characterized by tiny posterior salivary glands, a small triangular calamus and small almost circular ligula

Ethno-geochemical and phytolith studies of activity related patterns: A case study from Al Ma'tan, Jordan

Understanding Neolithic sites in southwest Asia is often difficult because of the lack of preservation of organic remains and the effects of various taphonomic processes that alter the original record. Here, we use an ethnographic approach to test the potential of using plant phytoliths and geochemistry to aid our interpretation of southwest Asian Neolithic sites. Our study of a recently abandoned stone and mud constructed village in Jordan, shows that for certain activity types, phytoliths and geochemistry can help distinguish different construction methods and functions, particularly for burnt areas, animal use areas and where there has been the addition of a specific construction material. For features constructed from the same source materials distinctions are more problematic. Geochemical and phytolith proxies were individually effective in distinguishing activity areas and construction materials, but signals were diminished when the statistical analysis was run on both forms of evidence combined. It is therefore recommended that the data from plant phytolith and geochemical analyses are subject to separate statistical tests and that the two sets of results are used in combination to interpret archaeological sites and their uses
