Abstract

Abstract The Mukdadiya Formation (Late Miocene–Pliocene) consists of alternations of red to brown sandstone and claystone layers in the Zagros Mountains Belt, northeastern Iraq. Two tracksites preserving bird and mammal tracks were recorded from the base of the formation in the Chamchamal area of the Kurdistan region in northeast Iraq. Avian tracks are large footprints with an average length of 25 cm that belong to Avipeda filiportatis. Mammal footprints imprinted by terrestrial cetartiodactyls belong to Pecoripeda amalphaea and Bifidipes velox, with cervids the most likely track makers. An unfamiliar large trace fossil on the studied slab, has symmetrical to asymmetrical marks, kidney or number-8-shaped and strong wrinkles on the surface. We interpret trace as having been produced by cetartiodactyls wallowing on the soft sediment surface. To accommodate this class of behavioral trace fossils; thus, we introduce a new fossilized behavior class, named “Laspichnia”, which includes a vertebrate mud-bathing imprint on a soft sediment surface.

伊拉克东北部库尔德斯坦Chamchamal地区Mukdadiya组(晚中新世-上新世)脊椎动物足迹和哺乳动物泥浴痕迹化石(Laspichnia)

摘要伊拉克东北部Zagros山脉带的Mukdadiya组(晚中新世—上新世)由红色—棕色砂岩和粘土岩层交替组成。在伊拉克东北部库尔德斯坦地区Chamchamal地区的地层底部记录了两个保存鸟类和哺乳动物足迹的足迹点。鸟类的足迹是平均长度为25厘米的大脚印，属于长翼鸟。陆生鲸脚类动物留下的哺乳动物脚印属于Pecoripeda amalphaea和Bifidipes velox，其中提供者最有可能留下足迹。被研究的石板上有一个不熟悉的大型化石痕迹，有对称或不对称的痕迹，肾形或数字8形，表面有强烈的皱纹。我们认为这些痕迹是鲸指动物在柔软的沉积物表面打滚时产生的。为了适应这类行为痕迹化石;因此，我们引入了一种新的行为类化石，命名为“Laspichnia”，其中包括在软沉积物表面上的脊椎动物泥浴印记。

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.
