Abstract
Two cladid crinoid species, ?Ulocrinus indicus Wanner, 1924, and ?Ulocrinus conoideus Wanner, 1937, are reinterpreted as cladid crinoids that do not belong to the cromyocrinids. This justifies Wannerʹs questioning of the generic assignment. ?Ulocrinus indicus has bifascial radial facets and is considered an advanced intermediate dendrocrinid assigned to the incertae superfamiliae, Katerocrinidae n. fam., Katerocrinus indicus n. gen., n. comb. This extends the range of the bifascial dendrocrinids upward into the Permian. ?Ulocrinus conoideus has trifascial radial facets and is assigned to the superfamily Scytalocrinoidea, incertae familiae, Dochmocrinus conoideus n. gen., n. comb. It re-emphasizes the need for revision of the family Scytalocrinidae. An unnamed, poorly preserved cup is described and considered to be a pelecocrinid crinoid, thus adding to the diversity of the West Timor Permian crinoids.
