摘要

在2011-2012年对Talmest遗址的研究中，发现了兽脚亚目动物和蜥脚类动物的足迹，并发现了其他石器动物，本文将对其进行分析。有两种基本类型归因于同一脊椎动物在淹没区底部产生的两种不同活动。一种类型(锥状)是由底部表面的滑动产生的，而另一种类型(前锥状)是挖掘、移除和积聚沉积物上层泥浆的结果。对结构的分析和可能的痕迹制造者得出的结论是，鱼石是一种淡水鱼在海底休息活动和寻找食物时产生的。

Cubichnia and Praedichnia in fossil ichnites of a flat fish from the Lower Cretaceous Talmest palaeoichnological site, Western High Atlas (Morocco)

Abstract During a study of the Talmest ichnological site (2011–2012), where theropod and sauropod tracks were discovered, other ichnites were found that are analyzed in the present work. There are two basic types attributed to two different activities produced by the same vertebrate at the bottom of a flooded area. One type (Cubichnia) is produced by sliding on the bottom surface while the other (Praedichnia) is the result of the excavation, removal and accumulation of mud from the upper levels of the sediment. The analysis of structures and possible trace makers leads to the conclusion that the ichnites were produced by a freshwater fish, during its resting activity on the bottom and during the search for food.

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.
