Brutalichnus
Brutalichnus is an ichnogenus. A case study from the Miocene of the Czech Republic found that Brutalichnus and two other ichnogenera have evidence of biting and gnawing traces on reptilian and mammalian bones. Brutalichnus contains one ichnospecies, Brutalichnus ''brutalis. The ichnogenera Machichnus and Nihilichnus were described in the same paper.
Wisshak, Knaust & Bertling consider Brutalichnus to be a nomen dubium''.
