This specimen is a very well preserved basal part of the beetle body (meso- and metathorax, and the abdomen).
Although it is lacking head, prothorax and appendages, an excellent condition of the rest of the body allows its reliable identification as a member of the the beetle family Elateridae (click-beetles; smeldere in Danish). I am not a specialist on Elateridae, so I cannot easily' identify the genus, but I am sure that so good degree of preservation displayed by this specimen will allow a genus (and possibly even a species) level identification by the experts. In recent time Elateridae is one of the large family of beetles, and popular object of taxonomic studies. Compared to other families Elateridae have relatively well known fossil record going back to late Jurassic (160-150 MYA). 12 fossil species of this family are described from Baltic amber, but most of amber material on Elateridae accumulated at the museums were not studied yet. At ZMUC there are 14 partially identified specimens of Elateridae, all awaiting proper examination. This newly found specimen from Agger does not match any of those at ZMUC, and actually it demonstrates the best quality of preservation. There is no doubt that ZMUC collection of Baltic amber will greatly benefit from the accession of this unique specimen, which will be very useful in the very needed study of the Tertiary amber fossils of Elateridae.
