Longtancunella is a genus of problematic brachiopod from the Lower Cambrian Chengjiang Lagerstätte. Its pedicle, which resembles the modern Chileates', is often preserved; the organisms often live in clusters of around a dozen attached to the same basal object (usually a shell or exoskeleton).{{Cite journal | last1 = Zhang | first1 = Z. | last2 = Holmer | first2 = L.
