摘要

摘要在美国新泽西州中西部晚三叠世斯托克顿组最上层河流沉积中，发现了Cruziana tenella和Helminthopsis等微量化石。鱼类群属于斯科耶尼亚鱼相。根据层理和原始沉积构造，认为该层为曲流环境下的沉积。在潮湿或潮湿的水道和点坝沉积物中，受空气暴露的大多数动物痕迹可能是由蠕虫状形式、线虫、无尾纲动物、多足类动物和节肢动物造成的。

Cruziana and Helminthopsis in fluvial deposits of the uppermost Stockton Formation (Late Triassic), west-central New Jersey

Abstract Fluvial deposits of the uppermost Stockton Formation (Late Triassic), west-central New Jersey have yielded the trace fossils Cruziana tenella and Helminthopsis isp. The ichnotaxa belong to the Scoyenia ichnofacies. On the basis of stratification and primary sedimentary structures, the beds are interpreted as deposits in a meandering stream environment. Worm-like forms, nematodes, notostracans, myriapods, and arthropods are probably responsible for most of the animal traces in moist or wet channel and point bar sediments subject to aerial exposure.

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.
