The Ledi-Geraru research area forms part the Lower Awash Valley (Afar, Ethiopia), a region with abundant sedimentary deposits which have yielded some of the most emblematic hominin fossil discoveries in the history of paleoanthropology. Ledi-Geraru is localized north of Hadar and Dikika, and west of Gona. A series of surveys carried out since 2002 have uncovered fossil-bearing sediments within the Lee Adoyta region, which include at least four fault-bounded blocks: the Bulinan, the Gurumaha, the Lee Adoyta and the Garselu. Abundant fossil vertebrate fauna have been recovered sampling a previously poorly known period between 2.84 to 2.58 Ma and which includes the earliest fossil attributed to the genus Homo ca. 2.8 Ma. The specimen LD 350-1 is a left hemi-mandible with P4 through M3 that was recovered from the Gurumaha fault block in 2013, which presents both primitive and derived characteristics attributable to the genus Homo. The vertebrate fauna associated with the mandible are typical of open grasslands but also indicate the presence of lakes and rivers. Some mammalian taxa have not been previously recorded in the lower Awash valley and show evidence of a species turnover that may be associated with climatic and environmental changes in the region. The 2015 field survey uncovered remains of at least three more hominin individuals and more fauna adjacent to the LD 350-1 site, reinforcing the potential of the Ledi-Geraru research area in answering key questions related to human evolution.
