Scleroctenophora is an extinct class of ctenophore, known from the Chinese Maotianshan shales of Yunnan. It is dated to Cambrian Stage 3 and belongs to late Early Cambrian strata. Scleroctenophorans are easily distinguished from other ctenophores by the presence of an internal skeleton that supports the body.
