The Lower Devonian of the Holy Cross Mountains is well-known in the field of vertebrate palaeontology but remains unrecognized as regards palaeoenvironmental reconstructions. We therefore analysed the spatial distribution and relative abundance of fossil vertebrates in this area within one time interval. The fauna from an Early Devonian (Emsian) si...

Among the hundreds of collected Devonian vertebrate macrofossils in the Holy Cross Mountains, placoderms dominate and provide data on their morphology, distribution and taphonomy. So far 17 out of more than 500 studied specimens have revealed bones with surfaces covered by sediment-filled trace fossils. The traces have been made on the vertebrate r...

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 ossif...

Porolepiform scales from the Lower Devonian of the Holy Cross Mountains, Poland, described from the ‘placoderm sandstone’ of the Daleszyce area, are revised. The aim of the present article is to organize the recently collected, but not formally described, porolepiform material from the Holy Cross Mountains, as well as specimens from erratic boulder...

The arthrodire placoderm, Dunkleosteus sp., is reported from the Upper Devonian (Frasnian) of the Holy Cross Mountains, Poland. The material comprises partially preserved remains of two individuals found in the Kellwasser-like horizon of the P³ucki locality. The remains are preserved as broken bone fragments redeposited from shallower environment i...
