origin of the coordinate system. In the x-axis, each one-meter interval was sequentially labeled with letters (A,B,C,D, etc.) and in the y-axis, each one-meter interval was sequentially labeled with numbers (1, 2, 3, 4, 5, etc.). The excavation of the site followed this grid and the unit's code refers to this system (e.g. L11, B13, Z14). Physical setting Lapa do Santo is located in Lagoa Santa region, eastern central Brazil. Lagoa Santa is an environmentally protected area comprising 360 km2. The vegetation is dominated by savanna (cerrado) and semi-deciduous forest. The rivers Mocambo, Samambaia, Jaguara and Gordura make up a tributary net that flows west to east to Velhas River, the main river in the area. Geomorphologically Lagoa Santa is a karstic terrain that can be divided into four distinct domains: 1) below 660 meters above sea level (masl) the terrain is characterized by a fluvial plain connected with the regional base level (Velhas River); 2) between 660 and 750 masl there is a karstic plain with dolines and lakes 3) between 750 and 850 masl there are karstic plateaus characterized by the presence of limestone outcrops (reaching up to 75 meters in height); 4) above 850 masl residual peaks composed of the non-soluble metasedimentary rocks from the Serra da Santa Helena Formation. The Lagoa Santa region geology comprises Sete Lagoas Formation and Serra da Santa Helena Formation, both part of the Upper Proterozoic metassediments of the Bambuí Group of the São Francisco craton. This cratonic cover metamorphosed during the Brazilian Cycle (700-450 million years ago) in a process that resulted in planar structures, such as lineation and foliation, and sub-vertical structures, such as normal and revert faults. The combination of these structures provides the path for the geomorphologic evolution that leads to the rockshelter configurations found in the region. The regional rockshelters and outcrops are developed in the limestone of the Sete Lagoas Formation. More specifically, Lapa do Santo rockshelter developed in the Member Pedro Leopoldo that is composed by very pure limestones with more than 90% calcite. The annual mean temperature is 23 °C, with lower temperatures (11 °C) occurring between June and July and higher temperatures (35 °C) occurring between October and November. The average humidity is around 65% in the dry season, from May to September, and around 85% on the rainy season, from November to April, with a pluviometrical mean of 1,400 mm/year. The major
