Gravicalymene Shirley, 1936,[1] is a genus of trilobites belonging to the order Phacopida, suborder Calymenina and family Calymenidae. Species included in this genus have previously been allocated to Calymene Brongniart 1822,[2]Flexicalymene Shirley, 1936. and Sthenarocalymene Siveter 1977.[3]
Wikimedia Commons has media related to Gravicalymene.
Rarest within the genus is the Middle Ordovician species Gravicalymene magnotuberculata, which is also amongst the rarest of all Calymenidae and regionally confined to two exposures in New York State. G. magnotuberculata is noted for its extremely pustulose exoskeleton, bell-shaped glabella and lack of complete articulated specimens.
