4.1. Feeding traces
Theropod tooth marks on bone often consist of either multiple
subparallel grooves made by several adjacent teeth in the dental
arcade (as from the teeth of the premaxilla; Hunt et al., 1994), or single scores where an errant tooth has contacted the bone (Currie
and Jacobsen, 1995). Marks of both kinds presumably result from
scraping movements in which the teeth are drawn over the carcass to
remove flesh for consumption.
