McNulty","doi":"10.1002/ajpa.70166","DOIUrl":"10.1002/ajpa.70166","url":null,"abstract":"&lt;p&gt;The Early Miocene locality called Meswa Bridge (0°08′10.2″ S, 35°12′20.9″ E), located near Muhoroni town in Kisumu County, Kenya, represents a small but important fossil deposit. Inferred to be close in age to the Oligocene-Miocene boundary, and as the type locality for the ape species &lt;i&gt;Proconsul meswae&lt;/i&gt; (Harrison and Andrews &lt;span&gt;2009&lt;/span&gt;), Meswa Bridge has particular importance for understanding the early evolution of Hominoidea. In the course of outreach efforts in this region, we discovered that the name “Meswa Bridge” is not recognized by the people who currently live near the fossil site. At their request, and to better represent the communities in which fossil excavations have taken place, we announce here a formal change of the name of this fossil locality to “Tonde Bridge.” Similar to previous locality name changes in Kenya (East Rudolf; West Stephanie), the National Museums of Kenya accession code (KNM-ME) will remain the same. Likewise, and at the stated preference of community leaders, this change would not impact taxonomic nomenclature that references the previous locality name (e.g., &lt;i&gt;Proconsul meswae&lt;/i&gt;).&lt;/p&gt;&lt;p&gt;We first became aware of the name discrepancy when working in the Koru region as part of the REACHE (Research on Eastern African Catarrhine and Hominoid Evolution) paleontological team. We inquired with people from that area about the location of “Meswa Bridge” and were led to a river crossing up in the hills. This, according to some Koru residents, was the Meswa River and hence was “Meswa Bridge.” However, we were nowhere near the place where Pickford (&lt;span&gt;1986&lt;/span&gt;) mapped the Meswa Bridge fossil locality—on the rift valley floor near Muhoroni—and, indeed, a short survey of the area returned no fossil remains.&lt;/p&gt;&lt;p&gt;We did relocate the original fossil locality, and although no fossil remains were found at that time, Pickford's (&lt;span&gt;1986&lt;/span&gt;, Fig. II-4: 27) coordinates and detailed map of the locality confirmed the location. In fact, the team did not expect to find fossils at Meswa Bridge, given the limited scope of fossiliferous deposits reported there (Andrews et al. &lt;span&gt;1981&lt;/span&gt;) and the history of excavation (see Harrison and Andrews &lt;span&gt;2009&lt;/span&gt;). Regardless, it was clear that local geographic names were inconsistent with names used by western researchers.&lt;/p&gt;&lt;p&gt;Recent outreach in that area by two of us (JS, COO) further clarified how the local community perceives the identity of the river and of the fossil outcrop. In cooperation with the Assistant County Commissioner of Muhoroni Division, the Chief of Tonde Location, and the Assistant Chief of the Tonde Sub-location, we convened a &lt;i&gt;baraza&lt;/i&gt; (meeting of different groups) to share with the community our knowledge of the ancient animals that once inhabited their land.
