Abstract
Remain of plesiosaurs are very rare in our German Lias formation and they are restricted mainly to isolated teeth and tooth remains, while of complete skeletons only a single specimen was known from the Upper Lias shales of Holzmaden. This specimen, found in 1893, is in the Museum für Naturkunde in Berlin, and was described, along with the other fragments then known ,by W Dames as Plesiosaurus guilemi imperatoris. The rarity of plesiosaurs in the German Lias is all the more surprising since the English Lias deposits have yielded a large number of skeletons, so that this animal group can in no way be called very rare, even if they did not appear in such herds as the much commoner ichthyosaurs.
