A new ichnospecies of Nihilichnus Mikuláš et al., 2006 from the Palaeogene of South America: trace makers and ichnological and palaeobiological implications
Dentalites on bones represent important evidence for revealing prey preferences and feeding ecology of extinct animals. Here, we present a new ichnospecies of Nihilichnus based on perforations on m...

In the case of N. fissuratus, the perpetuator was likely sparassodont metatherians, one of the few compelling evidence of this kind of predator-prey in the South American fossil record.

We describe a new ichnospecies, Nihilichnus fissuratus isp. nov., which are constituted of symmetrical marks on the mandibles, likely from antagonistic teeth.
