... grooves on its cortical surface, concentrated on the bone's distal end. At least 10 separate grooves of varying width are present, which we interpret to be scores made by theropod teeth. In addition, the tooth ichnospecies Knethichnus parallelum is present at the end of the distal-most groove. Knethichnus...

... with those produced by the feeding activity of an extant dental analogue to Theropoda. Striated tooth mark fossils in particular hold exceptional promise for identifying prehistoric consumer traits. These traces, recently described as the ichnotaxa Linichnus serratus and Knethichnus parallelum ( Jacobsen...

... to the ichnospecies Linichnus serratus ( Jacobsen and Bromley 2009 ). Additionally, the finely spaced traces on CNRST–SUNY 335 compare closely with those attributed to the serrate-toothed shark Squalicorax ( Schwimmer et al. 1997 ), and pertain to the ichnospecies Knethichnus parallelum ( Jacobsen and Bromley...
