Abstract

The earliest pottery yet found in the Western Hemisphere has been excavated from a prehistoric shell midden near Santarem in the lower Amazon, Brazil. Calibrated accelerator radiocarbon dates on charcoal, shell, and pottery and a thermoluminescence date on pottery from the site fall from about 8000 to 7000 years before the present. The early fishing village is part of a long prehistoric trajectory that contradicts theories that resource poverty limited cultural evolution in the tropics., AMAZONIA HAS BEEN DESCRIBED AS sparsely occupied by small Indian groups in prehistoric times. The resource poverty of the tropical forest habitat was thought to have precluded permanent settlement, population [...]

2. Operation of the Harwell UK 14C Data Base and its Expansion through Data Exchange with Other Laboratories

Author

Abstract

The use of computer data bases for storage and retrieval of 14C data is a logical application for the rapidly expanding numbers of 14C determinations. Harwell has established a data base for all samples originating from sites in the United Kingdom and Eire. The core of the data is the Council for British Archaeology's published Index of Radiocarbon Dates which we are expanding to include all Harwell UK dates released for publication by the submitters plus dates from other laboratories both within and outside the UK. As a demonstration of the feasibility of direct database-to-database communication, cooperation has been sought from Groningen and Oxford to transfer computer files containing 14C results for UK sites. Neither of these laboratories use the same system as Harwell for their in-house data base and this exercise highlights the importance of a transfer language for both the national and international schemes as it is no longer practical to carry out such procedures through keyboard typing.
