Abstract

Nanogomphodon wildi n. gen., n. sp. is based on a tiny lower postcanine tooth from the lower Lettenkeuper (Lower Keuper or Erfurt Formation; Ladinian) of Michelbach an der Bilz (Baden-Württemberg). It represents the first record of a traversodont cynodont from the Middle Triassic of Europe and exhibits a distinctive combination of dental features. Along with recent discoveries of other traversodont taxa from the Upper Triassic of eastern North America,Nanogomphodon indicates the existence of a distinct lineage of these cynodonts in the Northern Hemisphere.

Kurzfassung

Nanogomphodon wildi n. gen., n. sp. basiert auf einem winzigen unteren Postcaninen aus dem Unteren Lettenkeuper (Unterer Keuper oder Erfurt-Formation; Ladinium) von Michelbach an der Bilz (Baden-Württemberg). Diese neue Form repräsentiert den ersten Nachweis eines traversodonten Cynodontiers aus der Mittel-Trias von Europa und zeigt eine diagnostische Kombination von Zahn-Merkmalen. Zusammen mit neueren Funden von anderen traversodonten Cynodontiern aus der Ober-Trias im Osten von Nordamerika signalisiertNanogomphodon die Existenz einer eigenständigen Entwicklungslinie dieser Cynodontier auf der nördlichen Halbkugel.
