'''''Westergaardites''''' is an Upper Cambrian trilobite that is known from the Eastern Tian Shan (Central Asia). It is related to ''Triarthrus'', but can easily be distinguished from it by an extremely long exoskeleton, anteriorly placed eyes, a thorax of 19 segments with an extremely wide axis, and very narrow pleural regions, pleural spines, and a pygidium with marginal spines.<ref name="Treatise">{{cite book|last= Moore|first= R.C.|year= 1959|title= Arthropoda I - Arthropoda General Features, Proarthropoda, Euarthropoda General Features, Trilobitomorpha|publisher= Geological Society of America/University of Kansas Press|series= Treatise on Invertebrate Paleontology|volume= Part O.|pages=1–560|location= Boulder, Colorado/Lawrence, Kansas|isbn= 0-8137-3015-5}}</ref>
