| Abstract |
A series of osteological characters of Taverneichthys bikanericus from the continental Paleocene of India are studied, allowing specifying its systematic position within the Osteoglossidae. It is shown that on the basis of its peculiar snout morphology this species occupies an intermediate position between genera such as Chanopsis and Phareodus, which possess a primitive snout with a large dermethmoid reaching the frontals and separating the two nasals from each other, and such as Brychaetus, Musperia, Opsithrissops, Osteoglossum and Scleropages, which exhibit an evolved snout. The latter presents nasals, which are articulated to the frontals, meeting each other on the mid-line, except at their anterior edge, where a small dermethmoid, largely separated from the frontals, is inserted between. |
