Early Permian (Sakmarian) crinoids are described from six horizons in the Saiwan Formation of the Huqf area of southeastern Oman. Each horizon yielded only one to three taxa. All specimens lived in a shallow water environment characterized by mixed s

Late Paleozoic macroevolutionary crinoid faunas were dominated by dendrocrinids, replacing most of the camerata crinoids that had dominated the Early and Middle Paleozoic macroevolutionary crinoid faunas. Two dendrocrinid taxa, the Cromyocrinidae and

In north-west Europe, the Permian is limited to the New Red Sandstone and the restricted marine facies of the Zechstein, yet elsewhere it is constituted of thick marine deposits with an abundant shelly fauna. One of the most notable sites for the mar

The extensive Devonian marine deposits of South China have yielded few articulated crinoid cups or theca. Two Eifelian specimens, from the Gupa Member, are the first ones reported from the Yingtang Formation, Eifelian, from the Ma’anshan section, G

In a series of papers published between 1916 and 1949 Johannes Wanner assigned or reassigned more than 1700 crinoid specimens to 26 species or subspecies of Graphiocrinus. Nine of the 26 species were subsequently transfered to other cladid genera by
