摘要

Augerinoichnus是一种马蹄形结构序列，被解释为蠕虫类动物水平螺旋洞的沉积遗迹。该单种化石仅在美国新墨西哥州的早二叠世潮间带和低地海岸平原沉积物中发现。最近在德国西南部早二叠世近岸湖泊沉积物中发现的同种化石是新墨西哥州以外的第一个Augerinoichnus记录，扩展了该鱼分类群的古地理和古环境分布。显然，Augerinoichnus是在广泛的非海洋环境中形成的，从潮滩到内陆洪泛平原，在这些环境中，基质的凝聚力和稳定性以及稳定和可预测的食物资源使追踪者能够在开放的洞穴中觅食。

First record of the Permian nonmarine helical trace fossil Augerinoichnus from outside of New Mexico

Abstract Augerinoichnus refers to successions of horseshoe-shaped structures interpreted as sedimentary remains of horizontal helical burrows of worm-like animals. The monospecific trace fossil was hitherto only known from early Permian intertidal to lowland coastal-plain deposits of New Mexico, U.S.A. Recent discoveries of conspecific material in early Permian nearshore lacustrine deposits of southwestern Germany represent the first record of Augerinoichnus outside of New Mexico and extend the paleogeographic and paleoenvironmental distribution of the ichnotaxon. Augerinoichnus evidentally was made in a wide array of nonmarine settings that ranged from tidal flats to inland floodplains where substrate cohesion and stability as well as stable and predictable food resources allowed the tracemaker to forage in open burrows.

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.
