Drie maal Ursus
Cranium , Volume 5 - Issue 1 p. 8- 15
A left half mandible of a large Brown Bear, an incomplete right half mandible of a Cave Bear, and an isolated right upper canine of a Brown Bear are described and identified. The two mandibular specimens have lost all their teeth. The first fossil (Van Tuyll van Serooskerken collection) was found by fishermen in the Brown Ridge area of the North Sea and presumably comes from the Early Weichselian Brown Bank Beds (freshwater clays). The second find (Mol collection), from the eastern flatlands of the Rhine at Bislich near Wesel (G.F.R.), collected during sand-sucking operations, probably dates back to final Pleistocene times (Würm III = Weichsel III). The isolated canine (Hombroek collection) was found at the surface on the Meuse levels, an artificial plain of suckedup sand South of the Hook of Holland. Its age may be anything from Middle Pleistocene to (Early?) Holocene (Flandrian), in the last case perhaps introduced by Neolithic man. The author once again expounds his views on the untenability of Ursus deningeri VON REICHENAU, 1904, as a separate species and offers a number of arguments proving his case that this should be a nomen delendum. as was already emphatically suggested by EHRENBERG (Akad. Anzeiger Nr. 10, Akad. d. Wisa in Wien, math.-naturw. Klasse, 26 April 1928, 1-4). Fossils in question are either to be seen as early U. arctos or as early U. spelaeus. They represent a series of evolutionary morphological stages occurring at different localities at different stratigraphical times after the extinction of U. etruscus (close of the Early Pleistocene).
