Asaphidae
Asaphidae is a family of asaphid trilobites. Although the first genera originate in Upper Cambrian marine strata, the family becomes the most widely distributed and most species-rich trilobite family during the Ordovician. 754 species assigned to 146 genera are included in Asaphidae. Distribution Most Asaphinae are characteristic of Baltica. Isotelinae genera are concentrated in Laurentia. The genera of Nobiliasaphinae are distributed in tropical Gondwana and South China. The genera of Ogygiocaridinae occur in Avalonia, Gondwana and Baltica. Asaphidae asaphids were already fairly common during the Upper-Cambrian, when 14 genera are known from Australia, North- and South-China. The last members of the family died-out at the end of the Ordovician. Assigned genera Asaphidae contains the following genera: *'' Anataphrus'' *'' Araiocaris'' *'' Asaphellus'' *''Asaphus'' *'' Atopasaphus'' *'' Aulacoparia'' *'' Aulacoparina'' *'' Australopyge'' *'' Baltiites'' *'' Banqiaoites' ...

Birmanites
''Birmanites'' is a genus of trilobites in the order Asaphida, family ''Asaphidae''. They lived in the Ordovician period, from the Tremadocian age until the Lower Ashgillian age (488.3-449.5 million years ago). These arthropods were a low-level epifauna, fast-moving and detritivore. Distribution Ordovician of Canada, China, the Czech Republic, Ireland, Italy, Sweden, the United Kingdom; Llandeilo of China; Arenigian of Argentina, China.
