元谋猿人遗址地处金沙江流域的元谋盆地东南部，是我国重要古人类文化遗址之一。2023年7月至2024年1月，云南省文物考古研究所等单位联合对遗址东南部的郭家包梁子开展了考古发掘工作，发掘面积为200 m²，分属于不同海拔的四个发掘区同步发掘，发掘深度5~13 m，总发掘深度约29 m，共清理化石地层23层，含化石地层总厚度约15.2 m。经系统发掘，四个发掘区原生地层共出土大哺乳动物化石12727件、粪便化石112件。大哺乳动物化石中具有属种鉴定意义的标本共1070件，共包括4目13科18属19种，其余均为动物碎骨。动物考古初步分析中还识别出少量可能与古人类活动相关的动物碎骨化石。本年度发掘为进一步认识元谋猿人遗址地层堆积与环境背景等提供了重要材料。

The Yuanmou hominin site is located at the Jinshajiang River valley, southeastern of the Yuanmou Basin, and is a key and important paleoanthropological site in China. From July 2023 to January 2024, Yunnan Provincial Institute of Cultural Relics and Archaeology conducted a joint excavation at Guojiabaoliangzi that is located at the southeastern part of the site. In total, an area of 200 m² was excavated, including four sub-excavation areas in varied elevations. The depth of excavated stratigraphy ranges from 5 to 13 m, with a total depth of 29 m. Twenty-three fossil layers were identified, by a depth of 15.2 m. Through the systematic excavation, 12727 pieces of large mammal fossils and 112 pieces of coprolites were unearthed from the four excavation areas. There are 1070 large mammal fossils can be assigned to specific types, including four orders, 13 families, 18 genus and 19 speices, whereas all others are fragmented bones. Preliminary zooarchaeological analysis identified a few number of bone fragments that probably related to the intentional activity of hominins. The 2023 excavation provides important materials for further understanding of the stratigraphy and paleoenvironmental context of the site.
