| The crista prootica is a ridge or ledge of the prootic which runs antero-posteriorly along the side of the braincase above the otic capsule. |
| The otic capsule became somewhat separated from the rest of the braincase as a pair of petrosals. |
| It forms the floor of the braincase under the posterior part of the otic capsule. |
| Posterior to the formation of the crista parotica, the ventral part of the otic process splits. |
| This nerve carries the otic ganglion, which is derived from glossopharyngeal neurons. |
| A columellar system connects the tympanic membrane to the oval window of the otic capsule, as in other reptiles. |
