A fossil beetle from the Upper Buntsandstein (Röt-Folge, Lower Triassic) in Karlsruhe Durlach-Eisenhafengrund is described. The specimen is one of the oldest known beetle findings in Germany. According to its stratigrafic context, the finding layer can be correlated with the Voltzia-Sandstone (E-France), which also yielded fossil beetles. The silty matrix, in which the beetle occurs, is interpreted as seasonal playa sediment. The beetle was fragmented during extraction. The lack of diagnostic features of elytra, scutellum and pronotum does not allow to assign the specimen to a family. However, the elytral humeral callus, the set off pronotum with caudolaterally concave margins combined with the size of almost 15 mm allows a diagnostic distinction from other coeval Coleoptera at least in Europe. Therefore, it is justified to refer the specimen from Durlach-Eisenhafengrund to a new genus and species: Durlachia striata.
Although known and housed in German institutions since at least the 19th century, until now marine reptiles from the
Braunjura ß have never been described in detail. The strata have yielded plesiosaur, thalattosuchian and rare ichthyosaur
remains, all fragmentary, most likely due to their deposition in a shallow marine, high energy palaeoenvironment. Cervical
vertebrae, which are housed in the Staatliches Museum für Naturkunde Karlsruhe (State Museum of Natural History in
Karlsruhe), are described here and reveal the first elasmosaurid plesiosaurs reported to date from the German Dogger.
