摘要

本文回顾了世界范围内犬科动物和类犬科动物(creodon和hyaenid)化石足迹的记录，并对这类足迹的分类进行了评述，并报道了阿根廷布宜诺斯艾利斯省南部晚更新世Pehuen Co遗址的犬科动物足迹新记录。在比较已提出的鱼属和现代犬科动物与野外足迹特征的基础上，提出了一套鱼属和鱼种分类数据库。技术分类综述:beestiopeda Vialov, 1965;Canipeda Panin and Avram, 1962;Felipeda Panin and Avram, 1962;Pehuencoichnum Aramayo and Manera de Bianco, 1987b;Creodontipus Santamaría et al. 1989-1990;Sarjeant和Langston, 1994;和Quiritipes Sarjeant等人，2002。提出了鉴别这些鱼类群的关键，并对犬足目的诊断进行了修正。Pehuen Co新发现的犬科动物足迹与Pehuencoichnum gracilis Aramayo和Manera de Bianco, 1987b难以区分，该鱼种同属Canipeda gracilis (Vialov, 1965)。提出了一种修正的诊断。Pehuen公司最有可能的C. gracilis生产者是一种中型狐狸，类似于Lycalopex的现存代表。

Canid Paleoichnology: Taxonomic Review and Producers of Canipeda from the Late Pleistocene of Argentina

ABSTRACT This contribution reviews the worldwide record of canid and canid-like (creodont and hyaenid) fossil footprints, the taxonomy of this type of footprints, and reports a new record of canid footprints from the late Pleistocene Pehuen Co site of southern Buenos Aires province, Argentina. On the basis of the comparison of proposed ichnogenera and features of modern canid and felid footprints, a set of ichnogeneric and ichnospecific taxobases are proposed. The ichnotaxonomic review includes Bestiopeda Vialov, 1965; Canipeda Panin and Avram, 1962; Felipeda Panin and Avram, 1962; Pehuencoichnum Aramayo and Manera de Bianco, 1987b; Creodontipus Santamaría et al. 1989–1990; Tetrastoibopus Sarjeant and Langston, 1994; and Quiritipes Sarjeant et al. 2002. A key to discriminate these ichnotaxa is also proposed and the diagnosis of Canipeda emended. The new findings of canid footprints from Pehuen Co are indistinguishable from Pehuencoichnum gracilis Aramayo and Manera de Bianco, 1987b, and this ichnospecies is synonymized under Canipeda gracilis (Vialov, 1965). An emended diagnosis for C. gracilis is proposed. The most likely producer of C. gracilis from Pehuen Co is a medium-sized fox similar to the extant representatives of Lycalopex.

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.
