Middle Norian assemblage was found in massive limestones (biogerm) of the same massifs as Early Norian. In it, in addition to previous representatives of the species, we found also: Gablonzeria kiparisovae Punina, G. singularis Punina, G. dalnegorica Punina (PI. 3), Toechastraea plana Cuif, Retiophyllia fenestrata (Reuss), R. norica (Frech), Distichomeandra primorica Punina. The thickness of the Gablonzeria kiparisovae Beds in the type section (Sakharnaya Mountain) is about 180 m. This assemblage was found in association with bivalves Otapiria ussunensis chankaika (Voronetz}, Entolium cf. kolyaense Kiparisova; conodonts - Epigondolella abneptis (Huckriede), Metapolygnathus linguiformts Hayashi, etc.
