Recent collections from the Hanadir Shale (Llanvirn) include a more diverse trilobite fauna than was originally known. In addition to the previously described Plaesiacomia vacuvertis and Neseuretus (Neseuretus) tristani the following have been recognized: N. (N.) cf. tristani, P. sp. aff. P. ram, Kerfornella sp., Kloucekia sp., Ningkianolithus hanadirensis sp. nov., and asaphid indet. The fauna also includes graptolites, brachiopods, bivalves, ostracods, and orthocones. The trilobites confirm the 'Gondwanan' aspect of the fauna.
