摩洛哥中南部的晚石炭世苏斯盆地（Souss Basin）展示了一系列约1,800米厚的河流和湖泊沉积物，这些沉积物产出了各种植物、昆虫、叶肢介类、介形类、水母、鱼类的化石遗迹，以及少量的四足动物足迹。最近对苏斯盆地遗迹化石的探索发现了几个被践踏的表面，包括四足动物的足迹，这些足迹被分配给Batrachichnus丛（Woodworth，1900）。Limnopus（Marsh，1894），Dimetropus（Romer and Price，1940），and Ichniotherium（Pohlig，1892）.这些足迹可以被称为temnospondyl，基础synapsid（pelycosaurian），和diadectomorph trackmakers。苏斯盆地的适度多样的四足动物足迹组合很重要，因为它是非洲第二古老的四足动物足迹记录，也是北美和欧洲以外第二个著名的遗迹属鱼龙兽足迹记录。根据各种四足动物足迹和先前收集的植物和昆虫遗骸，苏斯盆地在晚石炭纪一定代表了一个完善的大陆生态系统。
The Late Carboniferous Souss Basin of south-central Morocco exhibits an approximately 1,800m thick succession of fluvial and lacustrine deposits that have yielded diverse fossil remains of plants, insects, conchostracans, ostracods, jellyfish, fishes, and few tetrapod footprints. Recent exploration of ichnofossils of the Souss Basin led to the discovery of several trampled surfaces including tetrapod footprints assigned to the plexus Batrachichnus (Woodworth, 1900). Limnopus (Marsh, 1894), Dimetropus (Romer and Price, 1940), and Ichniotherium (Pohlig, 1892). These footprints can be referred to temnospondyl, basal synapsid (pelycosaurian), and diadectomorph trackmakers. The moderately diverse tetrapod footprint assemblage from the Souss Basin is important because it is the second-oldest record of tetrapod footprints from Africa and only the second record of the well-known ichnogenus Ichniotherium from outside of North America and Europe. Based on the variety of tetrapod tracks and previously collected floral and insect remains, the Souss Basin must have represented a well-established continental ecosystem during the Late Carboniferous.
