IN BONE REPRESENTATIVITY ANALYSES. In this work FTI is applied in order to obtain more refined conclusions about the transport process involved in taphonomic history of these accumulations. Data of bone representation from Fazenda Nova tank (in Brejo da Madre de Deus Municipality, Pernambuco State), Jirau and João Cativo tanks (both in Itapipoca Municipality, Ceará State) and the fluvial deposits of Araras/Taquara (outcrops of the Rio Madeira Formation, Rondonia State) were used in this analysis. Using the Spearman's nonparametric correlation between bone representation and FTI, we observed the quantitatively homogeneous preservation of skeletal elements less and more transportable in Fazenda Nova and João Cativo tanks, what would be expected for deposits of natural tanks, which were influenced by non-selective depositional processes. In Jirau and Araras/Taquara assemblages the preservation was of less transportable elements. In markedly fluvial deposits, as Araras/Taquara, was as expected sorting of elements due to transport, whereas sorting observed in Jirau tank may have not been related to transport, but to other biostratinomic and diagenetic factors. Simulation with Voorhies Groups (VG) for the same deposits showed conclusions contrary to those observed by use of the FTI, revealing that the taphonomic inferences about transport based in the use of VG for Pleistocene Megafauna assemblages can be misleading.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
