'''''Westergaardites''''' is an [Upper Cambrian](/source/Upper_Cambrian) [trilobite](/source/trilobite) that is known from the Eastern [Tian Shan](/source/Tian_Shan) (Central Asia). It is related to ''[Triarthrus](/source/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](/source/Treatise_on_Invertebrate_Paleontology)|volume= Part O.|pages=1–560|location= Boulder, Colorado/Lawrence, Kansas|isbn= 0-8137-3015-5}}</ref>
