摘要

在新泽西州米尔福德附近的晚三叠世帕塞伊组的细粒粉砂岩中，首次发现了新泽西州纽瓦克超群中不规则枝晶石化石的证据。相关的痕迹化石包括Helminthoidichnites、Scoyenia、sponeliomorpha和爬行动物足迹Rhynchosauroides，代表了Scoyenia鱼相。相关的沉积构造包括干燥裂缝、雨滴印痕、交错层理和工具痕迹。Passaic沉积物沉积于浅水湖岸线条件下，受周期性陆上暴露的影响。

First record: Dendroidichnites (D. irregulare) in Late Triassic marginal lacustrine deposits of the Passaic Formation, west-central New Jersey

ABSTRACT Fine-grained siltstones of the Late Triassic Passaic Formation, near Milford, New Jersey have yielded the first evidence of the trace fossil Dendroidichnites irregulare in the Newark Supergroup of New Jersey. Associated trace fossils include Helminthoidichnites, Scoyenia, Spongeliomorpha, and the reptile footprint Rhynchosauroides, representing the Scoyenia Ichnofacies. Associated sedimentary structures include desiccation cracks, raindrop impressions, cross-bedding, and tool marks. The Passaic sediments were deposited under shallow water lacustrine shoreline conditions subject to periodic subaerial 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.
