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.
