Dipnoan remains are mainly known from the Middle and Upper Devonian deposits in the Holy Cross Mountains, Poland. The presence of this group in the Lower Devonian was suggested by feeding trace fossils apparently made by dipnoan fish. Recent studies confirm the occurrence of body fossils based on single skeleton elements. Fragments of heavily ossified mandible and skull-roof represent dipnoan remains appear to belong to a primitive ‘Dipnorhynchus’-like form. It supplements the knowledge on the Early Devonian ecosystem at the Holy Cross Mountains and dipnoan ichnological record is now supported by fossil remains of a putative trace-maker for Osculichnus isp.
