The upper part of the marine succession in the Idmarrach Formation and its laterally equivalent Tirhela Formation belong to the Bashkirian. More recent investigations of poorly preserved coral assemblages from the upper part of Idmarrach 2 section and the upper part of the Tirhela Formation are here described. The assemblage from the upper Idmarrach Formation comprises several typical Mississippian taxa, such as Aulophyllum fungites, Dibunophyllum bipartitum, Koninckophyllum interruptum, Siphonodendron scaleberense and Lithostrotion decipiens, and some highly evolved forms previously undescribed of Mississippian genera such as Haplolasma sp., Arachnolasma sp., Siphonodendron sp., Diphyphyllum sp., Solenodendron sp., Clisiophyllum sp. and a new species Corwenia tirhelensis sp. nov. In addition, an undetermined petalaxid has been also recorded. Similarly, the assemblage from near the top of the Tirhela Formation yielded some species regarded usually as Mississippian, such as Palaeosmilia murchisoni and Lithostrotion decipiens. We also identified the long-ranging tabulate Syringopora sp., Corwenia tirhelensis sp. nov., and a single species of the fasciculate rugosan, Siphonodendron tindoufense, previously described from Bashkirian rocks in the Tindouf Basin (southern Morocco). The presence of the latter taxon in both the Idmarrach and Tirhela sections implies a communication between the Adarouch region and the Saharan basins. The occurrence of S. tindoufense at the approximately same stratigraphic level in Tindouf, Taoudenni, Reggan-Ahnet and Adarouch, demonstrates its important regional stratigraphic value in North Africa. eng Atribución 3.0 España Coral assemblages of the Serpukhovian–Bashkirian transition from Adarouch (Morocco) journal article URL https://docta.ucm.es/bitstreams/7b26e96d-ae76-4d93-8404-ed2847cac28c/download File MD5 4011fa522aab65ea374eea7af23f8298 4627061 application/pdf Coral assemblages of the Serpukhovian–Bashkirian transition from Adarouch (1).pdf URL https://docta.ucm.es/bitstreams/b3ed6372-2bdf-4f92-977a-1d94179d69b2/download File MD5 43ec72ea8c116f8f8d09a99e98dc5761 55926 text/plain Coral assemblages of the Serpukhovian–Bashkirian transition from Adarouch (1).pdf.txt
