Platyceratidae is an extinct family of Paleozoic sea snails, marine gastropod mollusks. This family may belong in the Patellogastropoda or the Neritimorpha.[2] The platyceratid gastropods are known for the complex symbiotic relationships they had with crinoids.[3]
This is the only family in the superfamily Platyceratoidea.
