Paraceraurus is a genus of trilobites that lived in the Ordovician period (485.4 to 443.4 Ma). Its remains have been found in China, Estonia, Sweden and North America.[2] These trilobites have a rounded and moderately convex cephalon. Glabella is convex or flattened, with a sub-rectangular outline. Thorax shows eleven segments.[3]
