Abstract
Abstract We describe an isolated small stegosaur pes track from the ?Upper Jurassic-?Lower Cretaceous red beds of the folded Middle Atlas, Morocco. It comes from the base of the Oued El Atchane Formation which unconformably overlies the Middle Jurassic (Upper Bathonian-? Callovian) El Mers III Formation. The footprint is preserved as concave epirelief together with a natural cast on a fluvial sandstone slab and is assigned here tentatively to cf. Stegopodus isp. The new discovery confirms the presence of this ichnogenus on the African continent and highlights similarities between the Jurassic-Cretaceous dinosaur faunas of North Africa and those of Asia, North America and Western Europe.
摘要:我们描述了上侏罗统-?摩洛哥中阿特拉斯褶皱的下白垩世红层。它来自Oued El Atchane组的底部,该组不整合地覆盖在中侏罗统(上Bathonian-?Callovian) El - Mers III组。该脚印与河流砂岩板上的自然铸型一起被保存为凹面浮雕,在这里暂定为cf. Stegopodus isp。这一新发现证实了这种鱼属在非洲大陆的存在,并强调了北非侏罗纪-白垩纪恐龙群与亚洲、北美和西欧恐龙群之间的相似性。
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.
