Raspadita: a new lithic tool from the Isthmus of Rivas, Nicaragua

Determining precolonial botanical foodways: starch recovery and analysis, Long Island, The Bahamas

“…However, no ancient starches were recovered, which could be from multiple reasons such as micro-taphonomic issues of preservation (Haslam, 2004, Langejans, 2010 or processing plants which produce little or no starches (Hart, 2011). Alternatively, these tools could have been used to process fish (Debert and Sherriff, 2007). Lastly, maybe these pieces of limestone were not modified by humans and thus unused.…”

Laser scanning confocal microscopy: a potential technique for the study of lithic microwear

“…Lithic microwear analysis, along with residue analysis, has been fundamental to addressing these questions (Cahen et al, 1979;Donahue et al, 2002;Hardy, 2004;Keeley and Toth, 1981) and is a technique that relies principally on the use of reflected light microscopy at a range of magnifications; from what is termed low-power approaches (up to 100Â), which target principally fracture damage (Tringham et al, 1974), to 'high-power' approaches (100e400Â), which examine striations and changes in surface morphology in addition to fractures (Keeley, 1980). Scanning electron microscopy (SEM) is also used at magnifications principally ranging between 25 and 800 (Debert and Sherriff, 2007;Mansur-Franchomme, 1983). In all types of lithic microwear analysis data and images derived from experiments using stone tools to work, a range of materials are compared to wear traces observed on archaeological tools.…”

Uma Nota Sobre a Introdução De Raladores De Metal E Sobre a Produção E Consumo Da Mandioca E Do Milho Na Zona Costeira Das Guianas Durante O Século Xvii

“…Na verdade, esta é também a conclusão de Debert & Sheriff (2007) que analisou as chamadas "raspaditas" do sítio Santa Isabel (Nicarágua), representada por pequenas lascas ''pontudas''.…”
