Lituites is a peculiar genus of nautiloid cephalopod from the Ordovician Period. Its shell had a coiled tip. Juvenile Lituites did not have a conical part of the shell, they only had the coiled part of the shell. Then they later grew the conical part of the shell as they got older. Lituites was about seven inches long.
Lituites probably had to avoid predators such as Cameroceras and Anomalocaris. Lituites has been found in the United States (New York), China, Europe, and South America.
