Abstract
The Batocrinidae was a component of the North America Early Mississippian crinoid fauna and a significant contributor to the global biodiversity spike referred to as the “Age of Crinoids.” All batocrinids are North American, and all but one species are confined to the Tournaisian and Visean. In this contribution, genera are objectively defined on discrete characters, and the generic assignment of all valid species is re-evaluated. A phylogenetic hypothesis is presented for relationships within the Batocrinidae based on parsimony-based analyses and known stratigraphic ranges.Fifteen basic batocrinid architectural designs are recognized as genera, and four new genera are described: Glannearycrinus n. gen., Gongylocrinus n. gen, Magnuscrinus n. gen., and Simatocrinus n. gen. Batocrinus was a catch-all genus for any Mississippian camerate with tetragonal first primibrachials and an anal tube; thus, many late 19th century species are in need of a modern generic assignment. In this contribution, 61 percent of the 166 currently valid batocrinid species are reassigned to different genera. In addition, Sunwaptacrinus is transferred to the Batocrinidae, six species are transferred out of the Batocrinidae, and five species are designated as nomina dubia.Read the article »
