摘要

A new ichnofauna from the Permian of Morocco is described in details: it is the first Palaeozoic ichnofauna from the Zat Valley in Marrakech High Atlas. The new tracksite was found in the Tighdouine region, in the middle-upper Permian of the Cham-el-Houa Siltstone Formation. An abundant and diverse ichnoassemblage composed of both protostomian (probably arthropods and annelids) traces and vertebrate tracks is recorded. The presence of protostomian burrows and traceways, associated with tetrapod tracks corresponds to the Scoyenia ichnofacies. Protostomian traces are ascribed to Diplichnites gouldi, Diplopodichnus biformis, Scoyenia cf. gracilis and Spongeliomorpha carlsbergi. Tetrapod tracks include more than 70 tracks attributed to Amphisauropus, Erpetopus, Hyloidichnus, Characichnos, and indeterminate tracks. The co-occurrence of tetrapod tracks (both walking and swimming tracks), protostomian traces, mudcracks, ripple marks, as well as the lithological features of the track-bearing levels, indicate regularly inundated depositional environments during periods of high discharge under a local seasonal climate. A sedimentological analysis shows that the depositional environments evolved from braided-meandering systems to alluvial floodplains. The track-bearing surfaces are mainly preserved in crevasse splays, levees and pond deposits. This newly discovered ichnofauna helps to better reconstruct the palaeoenvironments of the Marrakech High Atlas in Morocco during the Permian, and enlarges the palaeogeographic distribution of important ichnotaxa.

Gracilis和Spongeliomorpha Carlsbergi。 Tetrapod轨道包括超过70个曲目,归因于Amphisauropus,Erpetopus,Hyloidichnus,Characichnos和不确定的轨道。 Tetrapod轨道(步行和游泳轨道)的共同发生(步行和游泳轨道),质子迹痕迹,泥浆,纹波标记以及轨道轴承水平的岩性特征,在当地季节性下的高放电期间指示定期淹没的沉积环境气候。沉积学分析表明,沉积环境从编织曲折系统演变为冲积泛源性。轴承表面主要保留在Crevasse Splays,Levees和Pond沉积物中。这次新发现的Ichnofauna有助于在摩洛哥在二叠纪重建Marrakech高地图集的古环境,并扩大了重要的ICHNotaxa的古地理分布。
