摘要

研究并描述了在伊米尔基尔发现的一个新遗址中的三种鸟类。四足动物的趾印、颚印和尾部痕迹的结构为区分以下两种类型提供了数据：真正的偶蹄目动物（有脚类动物的脚印和鳄鱼尾部的拖痕）；以及长足类动物的亚痕迹。大多数兽脚印是由于脚印壁坍塌而变形的，而蜥脚类亚痕迹则显示了大约十个分层良好的沉积层的强烈变形。我们可以看到的兽脚类和鳄鱼类虹膜的表面是追踪表面，即它们被印在上面的原始表面。

Crocodile tail traces and dinosaur footprints. Bathonian?- Callovian. Imilchil. High Central Atlas. Morocco

Three types of ichnites from a new site discovered in Imilchil were studied and described. The structures of pes and manus prints and tail traces of tetrapods provide data to separate: real ichnites (theropod footprints and crocodile tail drag marks); and sauropod’ subtraces. Most of the theropod footprints are deformed by collapse of their walls, the sauropod subtraces show the strong deformation of about ten well-stratified sedimentary levels. The surface on which we can see theropod and crocodile ichnites is the tracking surface, i. e. the original surface on which they were printed.
