"Mixosaurus cornalianus " has a sagittal crest associated with the expansion of the upper temporal fenestra . 33. Systematically, the presence of the antorbital fenestra is considered a synapomorphy that unites tetanuran theropods as a clade. 34. The temporal fenestra have been found with ossified fasciae, giving evidence of some type of a temporal muscle attachment. 35. The depression in which the antorbital fenestra is located, has a front end in the form of a lobe. 36. Neosauropods display a large opening in the skull located ventral to the antorbital fenestra , known as the preantorbital fenestra. 37. Neosauropods display a large opening in the skull located ventral to the antorbital fenestra, known as the preantorbital fenestra . 38. In fact, the namer of " Teraterpeton " first considered the hole to be an antorbital fenestra . 39. The skull frill is moderately long, and pierced by a large kidney-shaped parietal fenestra at each side. 40.
