Abstract A new ichnospecies, Linichnus bromleyi, is described on bone substrate as the result of a very likely predator/scavenger interaction. L. bromleyi consists of a single groove with a non-serrated edge. This new ichnotaxon is compared with L. serratus which was defined as a single elongate serrate-edged groove. L. bromleyi has been identified over the surface of bones of marine mammals (in particular, cetaceans and pinnipeds) from two Pliocene outcrops of Andalusia, southern Spain. The new ichnospecies can be clearly related with a trophic interaction between sharks and marine mammals (mainly whales, dolphins and seals).

Linichnus Jacobsen & Bromley 的新物种，2009

摘要 作为一种很可能的捕食者/清道夫相互作用的结果，在骨基质上描述了一种新的鱼类物种 Linichnus bromleyi。L. bromleyi 由具有非锯齿边缘的单个凹槽组成。这种新的鱼纲与被定义为单个细长锯齿边缘凹槽的 L. serratus 进行了比较。L. bromleyi 已在来自西班牙南部安达卢西亚的两个上新世露头的海洋哺乳动物（特别是鲸类和鳍足类动物）的骨骼表面上被发现。新的鱼类物种显然与鲨鱼和海洋哺乳动物（主要是鲸鱼、海豚和海豹）之间的营养相互作用有关。
