  • Dinosauria 2000
    Zbl. Geol. Paläont. 2001 Heft 3/4 93-144 Stuttgart, Teil II (-134) Nov. 2001 Literaturbericht Dinosauria 2000 H. HAUBOLD, Halle Die Berichte Dinosauria 1997-1998 und 1998-1999 (Zbl. II 1999 H. 1-2, Ref. Nr. 1-55 und 2000 H. 3-4, Ref. Nr. 238-332) finden nachstehend ihre Fortsetzung. Zusammen mit der Mehrzahl der bisher aus dem Jahr 2000 vorliegenden Publikationen sind einige Ergänzungen von 1999 behandelt. Der bemerkenswerte Zuwachs an Aktivitäten und resultierenden Ergebnissen hat sich auch in den im Jahre 2000 erschienen Schriften fortgesetzt. Das findet zunächst zahlenmäßig einen Ausdruck in den neu eingeführten Taxa: 4 Familien bzw. Subfamilien, 18 Gattungen und 22 Arten. Mit der Verteilung des Zuwachses bestätigen sich die Trends des letzten Jahrzehnts, indem sich die meisten neuen Arten auf Material aus China, aus den USA und aus der Mongolei beziehen. Stratigraphisch steht die Obere Kreide mit 10 neuen Arten an erster Stelle, gefolgt von 7 aus der Unteren Kreide. Im Ergebnis der Publikationen Ende 1990er Jahre zur phylogenetischen Taxonomie bzw. zu den Hypothesen der stammesgeschichtlichen Entwicklung der Dinosauria ist eine auffällige Stabilisierung zu verzeichnen. Der systematische Rahmen hat keine vergleichbaren Modifikationen erfahren wie in den Jahren zuvor (vgl. letzte Berichte). Allerdings hat die Arbeit von HOLTZ (A new phylogeny of the crnivorous dinosaurs: Gaia 15, 2000) bei Abschluß des Berichtes noch nicht vorgelegen.
