A restudy of the Barkhausen dinosaur tracksite shows that the track-bearing surface reveals considerably more detail than previously indicated, and a new map is presented, showing the trackways of nine sauropods, traveling north, possibly as a group. These are among the smallest sauropod tracks recorded in Europe. There is also evidence of two large theropods crossing the area, one moving to the south and the other to the west. Evidence of at least three other sauropods is registered in the form of isolated manus traces that represent larger individuals. Previous interpretations inferred that sauropod trackways trended south, and therefore suggested a predator chasing its prey as in the purported but controversial attack scenario claimed for the famous Paluxy River site in Texas. Based on the present study, this scenario is no longer tenable for the Barkhausen tracksite. The description of Elephantopoides barkhausensis (Kaever and Lapparent, 1974) shows that it represents a moderately wide gauge, but small manus sauropod and can be assigned under the ichnofamily label Parabrontopodidae. E. barkhausensis as originally defined was a nomen dubium, but it has since been re-described semi-formally, without renaming, we emend the description and assigned them to the ichnotaxon Parabrontopodus barkhausensis comb. nov. These tracks could have been produced by the small sauropod dinosaur taxon Europasaurus. The problematic ichnotaxon Megalosauropus teutonicus (Kaever and Lapparent, 1974), which represents a large three-toed theropod, is assigned to the recently described ichnogenus Jurabrontes from the Late Kimmeridgian of the Swiss Jura mountains as Jurabrontes teutonicus comb. nov. Furthermore, we attribute the theropod tracks from the time equivalent Langenberg quarry to the same ichnotaxon.

对晚侏罗纪恐龙足迹遗址巴克豪森(德国北部威恩山)的重新评估

对巴克豪森恐龙足迹遗址的重新研究表明,足迹表面显示的细节比以前显示的要多得多,并且呈现了一张新地图,显示了九只蜥脚类恐龙的足迹,它们可能作为一个群体向北移动。这些是欧洲记录的最小蜥脚类恐龙足迹之一。还有证据表明有两只大型兽脚亚目动物穿越该地区,一只向南移动,另一只向西移动。至少有其他三种蜥脚类恐龙的证据以代表较大个体的孤立手足踪迹的形式记录在案。先前的解释推断,蜥脚类恐龙的轨道向南移动,因此暗示有捕食者追逐猎物,就像在德克萨斯州著名的帕鲁西河遗址声称的但有争议的袭击场景一样。根据目前的研究,对于巴克豪森赛道,这种情况不再成立。的描述Elephantooides barkhausensis(Kaever 和 Lapparent,1974 年)表明它代表了一种中等宽度但较小的手蜥脚类恐龙,可以归入鱼科标签 Parabrontopodidae。最初定义的E. barkhausensis是一个nomen dubium,但此后它被半正式地重新描述,没有重新命名,我们修改了描述并将它们分配给 ichnotaxon Parabrontopodus barkhausensis梳子。十一月 这些足迹可能是由小型蜥脚类恐龙分类群Europasaurus 产生的。有问题的 ichnotaxon Megalosauropus teutonicus (Kaever and Lapparent, 1974),它代表一种大型三趾兽脚亚目,被分配到最近描述的 ichnogenusJurabrontes来自瑞士侏山脉的晚 Kimmeridgian 作为Jurabrontes teutonicus梳子。十一月 此外,我们将来自时间等效的 Langenberg 采石场的兽脚类足迹归因于相同的 ichnotaxon。
