The present work reports the results of a morphologic and taxonomic study of 377 specimens of free-living fossil polychaetes hold in the collections of the Museo Civico di Storia Naturale di Milano. The examined specimens come from the Cenomanian (Upper Cretaceous) Lagerstatten of Haqel (361), Hadjula (15) and Al-Namoura (1) (Lebanon). A systematic definition at species level has been possible for 110 specimens from Haqel and 2 from Hadjula so as 6 families (Aphroditidae, Didonidae n. fam., Eunicidae, Goniadidae, Lumbrineridae and Oenonidae, 7 genera (Didone n. gen., Eunicites, Ferragutia n. gen., Lumbriconerites, Palaeoaphrodite, Phoeniciarabella n. gen. and Teruzzia n. gen.) and 17 species (Didone pulcherrima n. gen. n. sp., Eunicites diopatroides n. sp., Eunicites falcatus n. sp., Eunicites joinvillei n. sp., Eunicites mariacristinae n. sp., Ferragutia cenomaniana n. gen. n. sp., Lumbriconereites garassinoi n. sp., Lumbriconereites hadjulae n. sp., Palaeoaphrodite libanotica n. sp., Phoeniciarabella caesaris n. gen. n. sp., Phoeniciarabella orensanzi n. gen. n. sp., Phoeniciarabella pinnulata n. gen. n. sp., Teruzzia gryphoeides n. gen. n. sp., Teruzzia pezzolii n. gen. n. sp., Teruzzia pusilla n. gen. n. sp. and Teruzzia sagittifera n. gen. n. sp.) of polychaetous annelids have been recorded from the Cenomanian fossiliferous levels of Lebanon. In addition to the results of the study of the examined material is reported a systematic appraisal of the fossil polychaetes where the taxa described from Cambrian to Eocene are listed with regard to the free-living forms.
