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 skull of the fennec fox is relatively short, broad over the braincase and tapers sharply toward the rostrum, forming a slender and narrow muzzle. |
The skulls of chinchilla rats have long and narrow rostra, a rounded braincase, enlarged bullae, and delicate zygomatic arches. |
During jaw retraction, the neck was straightened, thereby pushing the braincase anteriorly as the lower jaw was pulling the prey caudally. |
It forms the floor of the braincase under the posterior part of the otic capsule. |
The placoderms and chondrichthyans both show at least some capsular protuberance of the braincase, but the braincase is a single, undivided mass, whether or not ossified. |
