A new tuboid graptolite, Camarotubus graptocamaraeformis gen. et sp.n., is described from a calcareous erratic boulder of middle Ordovician (Caradoc?) age from Poland. This encrusting form combines characters of both the tuboid and the camaroid grapto-lites, and is regarded as a purely morphological intermediate between them. This finding supports Kozlowski's (1949) concept of a close phylogenetic relationship between the orders Tuboidea and Camaroidea
