The present paper describes new fossil materials (skull and some postcranial elements) collected in November 2020 in Engrunado cave in Nova Redenção municipality, Bahia, Brazil. This material was attributed to a sub‐adult specimen of Smilodon populator Lund, 1842, estimated to be 17–18 months old and with a body mass of 185 kg when it died. Based on its body mass, this individual could have hunted animals with a typical and maximum potential prey body mass of 302 and 1004 kg, respectively. Furthermore, it may have had a high dietary niche overlap with adult specimens of S. populator and other large carnivorans, such as Panthera onca (Linnaeus, 1758), probably hunting different species to avoid competition with them.
