Description
Summary:P5; The Chengjiang Lagerstatte has been celebrated for prolific soft-bodied fossils. Based on specimens recentlyexcavated in the Chengjiang Lagerstatte by the Early Life Institute, Northwest University, Diandongiapista Rong, 1974, isdirectly revealed to be a pediculate brachiopod, assigned to the Family Botsfordiidae, as is further confirmed by theexceptionally preserved vascular system including dorsal and ventral mantle canals. These specimens described hereinexhibit some peculiarities, notably the extremely thin and long pedicles, which suggest that Diandongia is epifaunal ratherthan burrowing brachiopod. A study of this group of animals indicates that they may be vital to understand the relationshipbetween the lingulids and the remaining brachiopods, and the character evolution of the early Cambrian brachiopods.
