Most lithic industries associated with hunter-gatherer groups in Eastern South America, especially the ones with points present, date to the Early Holocene, with some minor industries and lithic points typologies persisting until the Middle Holocene and, more rarely, until the Late Holocene.This is the case for the Garivaldinense lithic industry associated points typologies. In this article we present the technological analysis of the points identified at the Pororó site, located in central Rio Grande do Sul State, Brazil. The site is an artificial mound dated to around 2,500 BP. We applied an established protocol for analysis of stemmed points considering metric, morphological and technological features that allowed us to classify the artefacts in typologies. We identified two types of points associated to the Garivaldinense lithic industry: the Montenegro and Garivaldinense types. We have also identified a new type that has never been described before and proposed to refer to it as the Pororó type. At least one Pay Paso point was identified at the site, although this type of point is not yet known at other sites of this region and chronology. The results indicate persistence of the Garivaldinense Culture from the Early to Late Holocene, as well as technological innovation during the Late Holocene.
