A right femur referable to this species was recovered from fluvial sediments in Constitución 27 colony, Socoltenango municipality, in the southern State of Chiapas, Mexico. The femur shows the morphological characteristics ofE. laurillardi, such as: large size; rectangular shape, it is dorsoventrally flattened; lateral and medial margin rectilinear and parallel, and patellar trochlea transversely elongated with the medial margin in the sagittal plane of the femur. The record from Constitución 27 town, adds a new locality forE. laurillardiin Mexico, which adds to the previously known seven localities with remains of this species in Chiapas. In Mexico,E. laurillardiis present in 31 localities distributed in 13 states, mainly in the central and southern portion of Mexico, with an altitudinal range between 0-200 up to 2000-2500 meters above sea level, indicating a mostly tropical distribution of this species. 2022 artículo científico 1405-3322 https://www.redalyc.org/articulo.oa?id=94375432001 https://www.redalyc.org/journal/943/94375432001/ https://www.redalyc.org/journal/943/94375432001/html/ https://www.redalyc.org/journal/943/94375432001/94375432001.epub https://www.redalyc.org/journal/943/94375432001/movil https://doi.org/10.18268/BSGM2022v74n2a070322 en http://www.redalyc.org/revista.oa?id=943 Boletín de la Sociedad Geológica Mexicana application/pdf Sociedad Geológica Mexicana, A.C.
