The crinoid collection in particular deserves to be mentioned, containing many originals and types collected by Jaekel, Ubaghs, Sieverts-Doreck et al. The sea urchin collection incorporates the large collection of African explorer Georg Schweinfurth (1836-1925; Upper Cretaceous and Palaeogene from Egypt and the Middle East). Many recent Echinodermata are also part of the collection. Numerous Upper Cretaceous sea urchins were part of Gundolf Ernst’s collection.

Jurassic insects and crustaceans found in Sonthofen (coll. Schlotheim, Redenbacher) and Grimmen (coll. Ansorge) are well represented. Another excellent collection of arthropods from Hunsrueck Slate (Devonian, Germany) and the Crato formation (Lower Cretaceous, Brazil) and the holotype of Xenusion auerswaldae Pompeckj from a Lower Cambrian bedload should not go unmentioned. The latter is one of two known specimens of a connecting link between lobopods and arthropods.
