Reinvestigation of glacial erratic boulders from Jutland, Denmark, and from northern Germany,has revealed a moderately diverse fauna with the trilobites Holmiella? sp., Epichalnipsus anartanus,Epichalnipsus sp. A, Epichalnipsus sp. B, and Berabichia erratica, three species of lingulid brachiopods,one hyolith species, and trace fossils comparable to Halopoa imbricata. Comparison with faunasfrom the Cambrian of Scandinavia strongly suggested a biostratigraphic position equivalent tothe uppermost part of the (revised) Holmia kjerulfi–‘Ornamentaspis’ linnarssoni to lowermost Comluella?–Ellipsocephalus lunatus zones sensu Nielsen & Schovsbo (2011), or the lower to middle partof the traditional ‘Ornamentaspis’ linnarssoni Zone, but probably a particular horizon and biofaciesnot yet discovered in Scandinavia. Considerations of glacial transport regimes and the distributionof comparable rock units, as well as a petrographical analysis of the material from the studiederratic boulders and rocks from outcrops in Sweden, indicate that the boulders were derived fromthe Lingulid Sandstone Member of the File Haidar Formation and the source area is situated inthe vicinity of the present-day outcrops in the Halleberg–Hunneberg area, Västergötland, Sweden.
