Abstract: [eng] [cze]
The probability of misidentification of trace fossils is extremely high if the authors did not see the original material but used only published photographs. Clearly, it is impracticable to visit all the collections containing the revised material and impossible to visit all type localities, but further caution against the use of photos or drawings must be done here. Photographed material can result in the effect named here “photoseries”: just the method of illumination of the object can make it classifiable as two different ichnotaxa. Diffuse light enables an annulate tunnel to be featured as Rhabdoglyphus, but raking light depicts instead “invaginated segments” of Fustiglyphus of idealized drawings is obviously even more problematic, as shown by nice “graphoseries” if we consider the original specimen, the method of its preparation, and the published figure. Tafosérie jsou daleko rozšířenějším problémem v ichnotaxonomii, než bylo předpokládáno autory koncepce. Lze doložit, že jejich rozpoznání je téměř nemožné, když pracujeme pouze s literárními prameny, nikoliv s reálným, neselektivně sbíraným materiálem.
