Kurzfassung

Beschreibung von Knochenresten einer neuen Gattung der Choristodera der mongolischen Unterkreide (Lepidosauria):Khurendukhosaurus orlovi n. gen. n. sp. Die Familien-Zugehörigkeit, für die sich an die Champsosauridae denken ließe, bleibt freilich ungewiß, weil sich die zusammen mit den Langknochen gefundenen Wirbel stark von jenen der Champsosauridae unterscheiden. Sie lassen sich aber auch bei keiner anderen Tetrapoden-Gruppe unterbringen.

Abstract

This paper is devoted to the description of postcranial remains of a new genus of Choristodera,Khurendukhosaurus orlovi n. gen. n. sp., from the early Cretaceous of Mongolia. Its familial status is uncertain since the vertebrae which were found in association with these remains differ from all known vertebrae of Champsosauridae; they do not seem however, to belong to any other known group of tetrapods.

Résumé

Cet article est consacré à la description différentielle des restes postcraniens d’un nouveau genre de Choristodera,Khurendukhosaurus orlovi n. gen. n. sp., du Crétacé inférieur de Mongolie. Son appartenance familiale est incertaine, car les vertèbres qui ont été trouvées en association avec ces restes sont très différentes de celles des Champsosauridés; mais elles ne semblent pas non plus trouver place dans un autre groupe de Tétrapodes.
