Crinoidal debris is common from the basal parts of the open marine Khuff Formation in Oman; yet, little is known about the diversity and affinities of this fauna. Exallocrinus khuffensis n. gen., n. sp. is described from this unit, and is the first crinoid crown from outcrops of the Wordian, Lower Khuff Member, in the northern Huqf region of Oman. This new crinoid is among the youngest Paleozoic crinoids known, yet it has a combination of more stemward and crownward characters. Because of the uncertainties concerning the latest Paleozoic and earliest Mesozoic crinoid phylogeny, Exallocrinus n. gen. is questionably assigned to the Ampelocrinidae.
