Abstract

Abstract A new ichnospecies, Ereipichnus pickerillensis, is described from lower shoreface deposits of the Pliocene Casa Cruz Sandstone Member of the Moruga Formation on Trinidad. E. pickerillensis comprises horizontal and sub-horizontal tubular burrows that are lined with radially orientated, poorly imbricated bivalve and other small shell fragments. In the studied strata, E. pickerillensis is found in association with Zoophycos, Asterosoma, Thalassinoides, and other elements of the Cruziana ichnofacies.

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.
