 The specimen's preservation likely resulted from it having being deposited in sediment right side down, thus leaving the left side exposed to the elements.It received a field number of MT-II, and later a specimen number of AGB 6257 at the Anhui Geological Museum.In 2014, the specimen was described by Ryosuke Motani and colleagues in "Nature" as representing a new genus and species, "Cartorhynchus lenticarpus".
