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.

在这项工作中，对弓形虫的牙齿残骸进行了分析sp。（哺乳动物，Notoungulata）标本从巴拉圭的伊帕内河（YpanéRiver）河岸救出。几种技术被用来分析样品的不同地质方面，从而为理解化石过程以及牙齿残留物中存在的磷灰石中的古环境条件的含义提供了关键。样品中存在的化学物质通过拉曼光谱和傅立叶变换红外光谱（FTIR）进行鉴定，样品的化学成分通过能量色散X射线荧光（EDXRF）和X射线光电子能谱（XPS）确定，以及通过X射线衍射（XRD）进行的矿物学分析。值得一提的是，这项工作是巴拉圭开展的古生物学领域的第一项工作。
