Abstract
In this work, there were analyzed dental remains of a Toxodon sp. (Mammalia, Notoungulata) specimen rescued from the riverbank of the Ypané River in Paraguay. Several techniques were used to analyze the different geological aspects of the samples, thus providing keys to the understanding of fossilization processes and the implications of paleoenvironmental conditions in the apatites present in the dental remains. The identification of the chemical substances present in the sample was made by Raman and Fourier Transform Infrared (FTIR) spectroscopy, the chemical composition of the samples was determined using energy dispersive X-ray fluorescence (EDXRF) and X-ray photoelectron spectroscopy (XPS), and the mineralogy by X-ray Diffraction (XRD). It is worth mentioning that this work is the first in the area of Paleometry carried out in Paraguay.
