Abstract

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).

摘要:在骨基质上发现了一种新的鱼种——布罗姆利林鱼(Linichnus bromleyi)，这很可能是捕食者与食腐者相互作用的结果。龙舌兰由一个无锯齿边缘的单一凹槽组成。这个新的鱼分类群与被定义为单个细长锯齿边缘凹槽的L. serratus进行了比较。在西班牙南部安达卢西亚两个上新世露头的海洋哺乳动物(特别是鲸类和鳍足类)的骨骼表面上发现了L. bromleyi。这些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。

期刊介绍： The foremost aim of Ichnos is to promote excellence in ichnologic research. Primary emphases center upon the ethologic and ecologic significance of tracemaking organisms; organism-substrate interrelationships; and the role of biogenic processes in environmental reconstruction, sediment dynamics, sequence or event stratigraphy, biogeochemistry, and sedimentary diagenesis. Each contribution rests upon a firm taxonomic foundation, although papers dealing solely with systematics and nomenclature may have less priority than those dealing with conceptual and interpretive aspects of ichnology. Contributions from biologists and geologists are equally welcome. The format for Ichnos is designed to accommodate several types of manuscripts, including Research Articles (comprehensive articles dealing with original, fundamental research in ichnology), and Short Communications (short, succinct papers treating certain aspects of the history of ichnology, book reviews, news and notes, or invited comments dealing with current or contentious issues). The large page size and two-column format lend flexibility to the design of tables and illustrations. Thorough but timely reviews and rapid publication of manuscripts are integral parts of the process.
