Abstract
The functional morphology of Levitusia, based principally upon the type-species L. humerosa (L. Sowerby), is described and compared with living brachiopods. Levitusia sp. lived in tropical Dinantian seas with agitated waters and at shallow depths, perhaps no more than 50 m. The lithologies in which specimens are found support this view and indicate the need for some revision in the interpretations of some Dinantian sedimentary environments. Further evidence for the synonymy of L. christiani (de Koninck) in L. humerosa is presented.
