.... 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...

... Monobathrida and Diplobathrida. The first phylogenetic analysis identified a suitable outroup for rooting the Ordovician camerate tree and assessed affinities of the atypical dicyclic family Reteocrinidae. The second analysis inferred the phylogeny of all well-preserved Ordovician camerate genera. Inferred...

... of ‘cyathocrine’ cladids (sensu Moore and Teichert, 1978 ). A similar pattern was recovered by Guensburg ( 2012 , fig. 2). Building on these studies, Cole ( 2017 ) further assessed the basal split between camerates and non-camerates and tested the taxonomic status of the Monobathrida and Diplobathrida...

..., knowledge of the crinoids in South America has increased in the last two decades, but the South American fauna remains dominated by camerates, mainly of the order Diplobathrida. This crinoid fauna has no similarity with the fauna of South Africa (except by Ophiocrinus stangeri ), but has taxa associated...

... phylogenetic analysis for the early Camerata (a major subdivision of crinoids), thereby testing the monophyly of traditionally recognized higher taxa, including Monobathrida and Diplobathrida. Wright et al. ( 2017 ) present a phylogeny-based classification for crinoids, defining a number of major taxa...

... monobathrid affinities. The monobathrid assignment for Proexenocrinus was questioned in the Treatise on Invertebrate Paleontology (Ubaghs, 1978 , p. T441). Later, Proexenocrinus was revised, redescribed, and reassigned to the Rhodocrinitidae Roemer, 1855 , within the Diplobathrida Moore and Laudon...

In this contribution, we discuss all known taxa from the Brechin Lagerstätte that belong to Diplobathrida sensu Cole ( 2017 ) as well as the dicyclic stem eucamerates (i.e., reteocrinids). In a series of subsequent papers, we will address the monobathrid, cladid, disparid, flexible...
