“…This suggests that Goryeocrinus n. gen. can be classified into the Rhodocrinitidae. The family is the largest diplobathrid group for which no diagnostic combination of characters can be defined (Ausich, 1986;Ausich et al, 2002;Cole, 2017;Cole et al, 2018). It has been noted that systematic revision of diplobathrid families is inevitable and the recent analyses corroborate their paraphyly (Cole, 2017(Cole, , 2019Cole et al, 2018).…”

Goryeocrinus pentagrammos n. gen. n. sp. from the Jigunsan Formation of South Korea is described and is the first diplobathrid recorded from Middle Ordovician (middle Darriwilian) strata of East Gondwana. Phylogenetic analyses suggest that G. pentagrammos n. gen. n. sp. is a member of the paraphyletic Rhodocrinitidae of the Diplobathrida and most closely related to Paradiabolocrinus from the Late Ordovician (Sandbian) of Laurentia. Goryeocrinus pentagrammos n. gen. n. sp. is characterized by having a pentameral, flat bowl-shaped calyx, a conspicuous pentagrammatic ridge formed by bifurcated median ray ridge and pentagonal basal ridge, at least two interradials in the first row of regular interrays, an anitaxial ridge originating from the CD interray but close to the C ray radial, and lacking intrabrachials and interradials between secundibrachials. The occurrence of G. pentagrammos n. gen. n. sp. from South Korea (East Gondwana) drastically expands the Ordovician paleogeographic range of camerates, which otherwise have been recorded from Laurentia, West Gondwana, Avalonia, and Baltica.

Early and early Middle Ordovician crinoids are rare globally, and are best known from North America and the British Isles. The first Arenig crinoid from the Arabian Peninsula is Iocrinus sp. cf. I. subcrassus (Meek and Worthen), known from two near-complete individuals, and numerous fragmentary specimens and ossicles. These are the stratigraphically oldest Iocrinus specimens, and provide an unexpected extension of the palaeogeographical range of a genus known otherwise from slightly younger deposits in Laurentia (North America) and Avalonia (Wales). The Oman specimens differ from Gondwanan Heviacrinus melendezi Gil Cid et al., currently classified as a maennilicrinid, but morphologically close to Iocrinus, in having arms that branch at least seven times instead of four and in having columnals typical of Iocrinus. Three species from Wales and the Welsh Borders, previously placed in Iocrinus, but differing in having smooth, conical dorsal cups, are reclassified as Margoiocrinus Donovan gen. nov., type species Iocrinus shelvensis Ramsbottom.
