Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Anquetin and C. Püntener 2020 | Solnhofia brachyrhyncha is diagnosed as a representative of Solnhofia by the full list of characteristics provided for this taxon above. Solnhofia brachyrhyncha differs from Solnhofia parsonsi by having a shorter and broader cranium (only slightly longer than wide), a shorter upper triturating surface that is wider posteriorly with a slightly sinusoidal labial margin, a palatine that does not contribute to the triturating surface nor partially floors the narial passage, a processus inferior parietalis that forms most of the anterior and posterior margin of the foramen nervi trigemini and that has a broader contact with the pterygoid behind that foramen, a reduced lateral exposure of the epipterygoid without blunt process, a processus trochlearis oticum more oblique in dorsal or ventral view and less concave in anterior view, a reduced contribution of the prootic to the processus trochlearis oticum, choanae limited to the palatines, a more developed processus pterygoideus externus, a condylus mandibularis situated anterior to the level of the occipital plane, a longer ventral exposure of the parabasisphenoid, a mandible about as wide as long with a short symphysis, a large laterally projecting dentary tubercle, a shorter lower triturating surface that widens greatly posteriorly and has a concave labial margin, a stouter and shorter coronoid process with a striated upper part, a greater anterodorsal development of the surangular (hidding much of the coronoid body in lateral view), a splenial positioned more anteriorly along the mandibular ramus, a foramen intermandibularis medius formed only by the dentary and splenial (no contribution from the coronoid), costo-peripheral fontanelles extending more anteriorly (to costal 1) and posteriorly (beyond costal 5) along the costal series, and an escutcheon shaped central plastral fontanelle. |
