Aus den altpleistozanen Hohlenfullungen des Steinbruchs Hollitzer bei Bad-Deutsch-Altenburg (Niederosterreich) wurden uber 100 Ursidenreste geborgen. Neben isolierten Zahnen und Elementen des postcranialen Skeletts liegen auch ein Armskelett in situ und ein fast kompletter Endocranialausguss ("fossiles Gehirn") vor, die sonst unmogliche Vergleichsstudien ermoglichen. Die Barenreste gehoren einem urtumlichen Vertreter der Braunbaren-Gruppe an. Die Funde von Deutsch-Altenburg sind auch fur die Phylogenie und die Verbreitungsgeschichte der Grossbaren von grosser Bedeutung, weil sie als geologisch alteste Braunbarenreste bisherige Theorien in Frage stellen und weil somit die Aufspaltung in die Braunbaren-Gruppe und in die Hohlenbarengruppe schon vor dem Altpleistozan erfolgt sein muss. Die verschiedenen Moglichkeiten des Aufspaltungsmodus werden diskutiert....Over 100 ursid remains have been retrieved from the Early Pleistocene cave fillings of the Hollitzer quarry near Deutsch-Altenburg (Lower Austria). Apart from isolated teeth and postcranial (skeleton) elements, there are also one in situ forelimb and an almost complete natural endocast of a brain ("fossil brain"), which enable otherwise impossible comparative studies. The ursid remains belong to a primitive representative of the brown bear group. The discoveries at Deutsch-Altenburg are also of great importance to the phylogeny and the distribution history of the ursids, because, as the geologically earliest brown bear remains, they cast doubt on previous theories, and because the split into the brown bear group and the cave bear group must have happened before the Early Pleistocene. Various possible divergence modes are discussed.
