University of Hannover on erratics of this type ("Kugelsandstein", "Old-Red-Sandstein"). The main questions concern the petrography, cement type and diagenesis. Because much of the erratics in North Germany are rich in apatitic remains (Arthropoda, Heterostraci, Crossopterygii and other fishes) that I have also examined them along the way. Because I have no experience in working with fossil fishes, I made contact with fish workers especially in the Baltic States.
Several groups of fishes can be deduced from scales: acanthodians with a problematic scale fauna and Psammosteiformes. The scale Porolepis posnaniensispoints to a lower Middle Devonian age. A complete unknown for Werner is the scale shown in the photo below. Does anyone has an idea, about the taxonomic position of this scale? Please send relevant reprints.
