The quarries located to the south of Visé, in southeastern Belgium, correspond to historical type area of the Viséan Stage (Carboniferous, Mississippian) and yielded an extremely rich macrofauna (known as the Visé fauna), including mainly brachiopods and mollusks (bivalves, gastropods, cephalopods), and also corals, trilobites and bryozoans, that are found in institutional collections all over the world. The Visé fauna is of late early Warnantian (late Asbian) age and was essentially recovered from a microbial buildup of Cracoean affinities that was exploited only in the quarries F and G sensu Horion and Gosselet’s (1892) terminology. Only the rugose corals have been revised, and the rest requires a complete taxonomic reassessment. Brachiopods are particularly diverse, and many genera (Productida, Orthida, Rhynchonellida, Terebratulida) were established in the past on the basis of type species from Visé. Productides are by far the most common elements of the brachiopod association, with the development of aberrant morphologies (Proboscidella, Striatifera). Some terebratulides and mollusks display ‘colour’ bandings that have been preserved. Two so-called Carboniferous species described by de Koninck (1887), namely Rhynchonella solitaris and Spirifer capillaris, are middle or late Frasnian in age.

位于比利时东南部 Visé 南部的采石场对应于 Viséan 阶段（石炭纪，密西西比州）的历史类型区域，并产生了极其丰富的大型动物群（称为 Visé 动物群），主要包括腕足类动物和软体动物（双壳类动物、腹足类动物） 、头足类动物），以及珊瑚、三叶虫和苔藓虫，它们在世界各地的机构收藏中都有发现。Visé 动物群处于 Warnantian 晚期（晚期 Asbian）时代，基本上是从 Cracoean 亲缘关系的微生物积累中恢复的，这种积累仅在采石场 F 和 G sensu Horion 和 Gosselet (1892) 的术语中被利用。只有皱纹珊瑚被修改了，其余的需要一个完整的分类重新评估。腕足类动物特别多样，有许多属（Productida、Orthida、Rhynchonellida、Terebratulida) 是过去在 Visé 的模式种的基础上建立的。Productides 是迄今为止腕足动物协会中最常见的元素，随着异常形态的发展（长鼻目、纹状体）。一些 terebratulides 和软体动物显示出已保存的“彩色”条纹。de Koninck (1887) 描述的两个所谓的石炭纪物种，即Rhynchonella solitaris和Spirifer capillaris，处于弗拉斯阶中期或晚期。
