Abstract
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.
