Asaphidae
Extinct family of trilobites
From Wikipedia, the free encyclopedia
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.[citation needed]

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. [1]
Asaphids first appeared in the Upper Cambrian,[2] and were already fairly common during this time, 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.[1]
Subdivisions and genera
More than 20 subfamilies have been named within the Asaphidae, but very few of the subfamily names are in regular use.[2] Over 150 genera of asaphids have been named.[2]
