Abstract
Abstract The ichnospecies Gastrochaneolites dijugus Kelly and Bromley 1984 and Teredolites longissimus Kelly and Bromley 1984, attributed to the boring activity of gastrochaenoid and pholadid bivalves, are described respectively from the Miocene Vilanova Basin and the Pliocene Almería-Níjar Basin. Miocene and Pliocene traces are preserved as positive casts associated to invertebrate shells and wood fragments, respectively; in both cases, the host substrate (shells and wood) has been lost almost entirely by different taphonomic processes (mainly dissolution). For the first time in the fossil record, the complete ichnogenetic sequence of these two ichnospecies is described and figured.
摘要描述了中新世Vilanova盆地和上新世Almería-Níjar盆地中新世gastrochaeolites dijugus Kelly and Bromley 1984和Teredolites longissimus Kelly and Bromley 1984两种鱼种，这两种鱼种分别归因于gastrochaenoid和pholadid双壳类的钻孔活动。中新世和上新世的痕迹分别被保存为与无脊椎动物贝壳和木头碎片相关的正面铸型;在这两种情况下，宿主基质(贝壳和木材)几乎完全通过不同的埋藏过程(主要是溶解)丢失。在化石记录中，首次对这两种鱼的完整的鱼成序列进行了描述和描绘。
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.
