Despite being the second most diverse mammalian order, bats remain relatively understudied in the fossil and subfossil record. In Brazil, numerous living species have been identified in cave deposits, although few fossils have been dated, with none originating from the Holocene. This study presents a specimen from the Middle Holocene, collected from Cuvieri Cave. The fossil consists of an incomplete, U-shaped mandible that includes the first molars. The specimen was identified as Artibeus sp., a genus of fruit-eating bats that is currently widespread across Brazilian territory. This specimen originates from a poorly understood temporal interval in the Lagoa Santa region, coinciding with the apparent abandonment of the area by human populations (referred to as the Archaic Gap) and during which the faunal population of Cervidae experienced a notable decline in the number of fossil records. The genus Artibeus is widely distributed in tropical regions and is commonly found in environments ranging from semi-arid regions to savannas and dense forests. It is not considered a paleoenvironmental indicator.
