Taphonomy of a novel small carnivore: experimental analysis of honey badger (Mellivora capensis) modifications on leporid prey

Abstract

The honey badger is a widespread, but understudied African carnivore, with high potential as a bone accumulator in cave and fossil deposits. This study serves as the first investigation into the taphonomic modifications of this species when feeding on small to medium-sized prey. Domestic rabbit (Oryctolagus cunniculus) carcasses where fed experimentally to a breeding pair of captive honey badgers housed at the Johannesburg Zoo. Bones from the feeding refuse and the carnivore scats were analysed for anatomical composition, fragmentation patterns, tooth marks and digestion. The results were compared with feeding studies with various small carnivores on leporid prey. Honey badgers preferentially opened their prey at the belly and focussed their feeding on nutritionally high-yield soft parts, often discarding low-yield parts like distal appendages, crania and the skins. Bones from the refuse assemblage were often complete and unmodified but stripped of flesh. Bones from the scat assemblage displayed very high fragmentation, light digestive modification and high numbers of tooth marked bones. This latter character was particularly diagnostic for the honey badger. This study investigates a carnivore that has received little interest and shows the high potential of this carnivore to act as a bone accumulator. Further taphonomic research into this species will greatly enhance our understanding of this species and its activity in the fossil record.
