A note on an early Jurassic ophiuroid from Rachecourt (Lorraine, Belgium)

A fairly well-preserved ophiuroid, collected from micaceous sandy argillites of the Messaney Formation (Domerian, late Pliensbachian) as exposed at Rachecourt (Gaume, Belgian Lorraine) is described and tentatively identified as Sinosura wolburgi (Hess, 1960). The rarity of complete ophiuroid fossils in Belgian Jurassic deposits and the poor fossil content of the Messaney Formation (bioelastic beds, crinoid columnals) warrant description of the present specimen.
