Soomaspis
''Soomaspis'' is a genus of small to average size (about 3 cm or 1.2-inch long) marine arthropods in the Liwiidae Family, that lived during the late Ordovician (early Hirnantian).〔''Fossil Lagerstätten'', a catalogue of sites of exceptional fossil preservation, produced by MSc Palaeobiology students at University of Bristol's Department of Earth Sciences, web: (lagerstatten ).〕 Fossil remains of ''Soomaspis'' were collected from the Western Cape, South Africa. ''Soomaspis'' looks like a large, soft agnostid trilobite. It has a headshield (or cephalon) wider than the tailshield (pygidium), and in between them three thoracic body segments (somites). The genus is monotypic, its sole species being ''Soomaspis splendida''. == Etymology == The name of the genus is a compound word of the deposit where the species was collected (the Soom Shale), and the Greek word ''"aspis"'' (shield). The species epithed, ''splendida'' comes from the Latin word ''"splendere"'' (brightness).
