Levisoceras is a genus of early Ordovician ellesmerocerid cephalopods.[1] [2]
Levisoceras is a distinctive ellesmeroceratid that combines rapid expansion a strong endogastric curvature. The cross section is compressed with the height increasing more rapidly than the width. The siphuncle is ventral and expands much as the shell itself.[1] In one specimen[2] the height was found to be around four centimetres and the width 2.5 cm. The septa are approximately flat.
