| 41. | A premaxilla, among the newly discovered material, led to the reassignment of " Chalawan " to the Pholidosauridae.
|
| 42. | The premaxilla counts with two teeth rows : the outer row has three cusps, the central of which is the longest.
|
| 43. | It was solely known from the holotype premaxilla 104 / 3106 housed at Saratov University, however the specimen is probably lost.
|
| 44. | The anteriormost teeth, or carinae, of the premaxilla set in " Nicrosaurus kapffi " are enlarged and strongly curved.
|
| 45. | Like the coelophysoids, " Daemonosaurus " has a kink in its upper jaws, between the maxilla and the premaxilla.
|
| 46. | Early theropods and orthithosuchids have a toothless gap between the premaxilla and the maxilla, distinguishing them from " Smok ".
|
| 47. | The skull of the short-finned pilot whale has a shorter and broader rostum with a premaxilla that covers more of the maxilla.
|
| 48. | Also absent are the premaxilla, orbitosphenoid, symplectic, posttemporal, and supratemporal bones, the gill rakers, and the branchiostegal rays.
|
| 49. | Linkage mechanisms are especially frequent and manifold in the head of bony fishes, such as wrasses, which have protrusion of the premaxilla.
|
| 50. | In his reconstruction of the skull, Merriam illustrated the rostrum as being straight and showed six conical, striated teeth on the premaxilla.
