Lithotrochus is a genus of marine trochid gastropods mainly known from the Early Jurassic epoch of South America.^[1]^[2]^[3]^[4] While long considered endemic to the fossil record of South America, findings from the Pogibshi Formation of Alaska suggest that the genus expanded its paleogeographical range from the Northern Hemisphere to South America during the Jurassic.^[5]
