Zolhafah bella
Taxonomy
Zolhafah bella was named by Lapparent de Broin and Werner (1998). Its type specimen is TUB Vb-173, a partial skull (partial skull without mandibles), and it is a 3D body fossil. Its type locality is Ammonite Hill interdunal channel 31 (271080/1), which is in a Maastrichtian coastal sandstone/claystone in the Dakhla Formation of Egypt.

Diagnosis

|---|---|---|
| F. Lapparent de Broin and C. Werner 1998 | Bothremydid belonging to the Bothretnys group by the presence of pits in the posterior part of the enlarged triturating skull surfaces, in the maxilla, the jugal and the palatine. Zolhafah bella n.g., n.sp., differs from Bothremys cooki Leidy, 1865 and Rosasia Carrington Da Costa, 1940, principally by its more rounded snout, absolutely not medio-anteriorly prominent, its more shortened posterior skull part, its basioccipital and basisphenoid wider and its basiphenoid shorter than in both others, from Rosasia, at least, by its flat posterior palate (absence of podocnemidoid fossa) and: as in B. cooki, the choanae are at the level of the triturating pits (apomorphic characters). Its triturating pits are intermediate in depth between Rosasia and B. cooki. Its external nostril is much larger, higher and wider (plesiomorphic) and it is more vertical than in B. cooki. Moreover, Zolhafah bella n.g., n.sp., differs from Bothremys cooki and Rosasia by many details such as its frontal being longer than the prefrontal, its elongated orbits smaller than in Rosasia, larger than in B. cooki (where they are subcircular) and its higher anterior premaxillary surface (plesiomorphic characters), its maxilla more developed below the orbit than in B. cooki (in the latter. the orbit is higher than in Rosasia) and its ventral premaxillary-maxillary border thickened as in Rosasia, but still thicker than in Rosasia (apomorphic) (thin in B. cooki). Its anterior palatine sulcus between the triturating surfaces is shorter (apomorphic) and wider (plesiomorphic) than in both others. Its palatino-pterygoid suture is relatively wide, as in B. cooki, compared to Rosasia where it is narrowed. The occipital condyle was slightly posterior to the articular processeso f the quadrates,p robably as in Rosasiaa nd B. woki, and located less forward than in B. harheri. Size of Rosasia and B. cooki, much smaller than B. hurheri (Schmidt. 1940). | |
