摘要

与其他生物侵蚀痕迹相比，脊椎动物遗骸和无脊椎动物痕迹的关联虽然研究较少，但却提供了重要的古生态学信息。本报告描述了在乌拉圭发现的雕齿兽真皮骨骼遗骸中发现的Cubiculum ornatum Roberts, Rogers, and Foreman 2007, Osteocallis Roberts, Rogers, and Foreman 2007和其他未识别的昆虫痕迹。它们分别来自晚渐新世的弗赖本托斯组、晚中新世的卡马乔组和晚更新世-全新世早期的多洛雷斯组。报告的痕迹可能是由食肉甲虫留下的，这表明参考地层单元的沉积条件是温暖气候下的干燥期。

Insect trace fossils in glyptodonts from Uruguay

Abstract The association of vertebrate remains and invertebrate traces, although less studied than other bioerosion traces, provides important paleoecological information. This report describes Cubiculum ornatum Roberts, Rogers, and Foreman 2007, Osteocallis Roberts, Rogers, and Foreman 2007 and other unidentified insect traces from the dermal skeletal remains of glyptodonts found in Uruguay. They come from the Fray Bentos Formation (Late Oligocene), the Camacho Formation (Late Miocene) and the Dolores Formation (Late Pleistocene-Early Holocene). The reported traces were likely made by sarcosaprophagous beetles, which indicate depositional conditions with dry episodes in a warm climate for the referred stratigraphical units.

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.
