During jaw retraction, the neck was straightened, thereby pushing the braincase anteriorly as the lower jaw was pulling the prey caudally. |
|
The outer wall of the braincase becomes the alisphenoid and the dermal skull bones. |
|
It forms the floor of the braincase under the posterior part of the otic capsule. |
|
The otic capsule became somewhat separated from the rest of the braincase as a pair of petrosals. |
|
This reduces the importance of the stapes in supporting the braincase ventrally. |
|
In the adults of most vertebrates, the braincase is largely fused into a single solid mass. |
|
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 skulls of chinchilla rats have long and narrow rostra, a rounded braincase, enlarged bullae, and delicate zygomatic arches. |
|
The bulk of the muscle mass was located in an adductor chamber between the braincase and the dermal skull bones. |
|
In bony vertebrates, endochondral bones form from centers of ossification in the chondrocranium, although much of the braincase often remains cartilage. |
|
In short, the only part of a snake's skull incapable of movement is the braincase. |
|
The only compact unit is the central braincase, with all other skull bones little more than attachments held in place by ligaments and muscles. |
|
Thus, he was able to determine the conduit of nerves and blood vessels and the position and shape of glands, organs, and the braincase. |
|
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 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. |
|
The braincase box, as I understand the term, does not open up posteriorly, and there is nothing between the basal tubera which are, in fact, at least slightly pedunculate. |
|
Greatest width of braincase measured perpendicular to long axis of skull between posterior margins of zygomatic arches. |
|
The skull, although very similar to that of the least weasel, is relatively longer, with a narrower braincase. |
|
The braincase is concentrated through the nasal passage to the front and is correspondingly higher, with individual cranial bones that overlap. |
|
Substantial flattening of the braincase had occurred during fossilization of the specimen. |
|
|
The most remarkable aspect of this skull is the broadness and flatness of its face something previously associated with much more recent hominins in conjunction with a smaller, ape-sized braincase. |
|
The walls of the braincase are bony but lack supratemporal and postfrontal bones. |
|
Laia's relatively small braincase falls within the range of modern African monkeys, gibbons and siamangs. |
|
The braincase has distinctive chimp features but the teeth and face have human characteristics. |
|
Two key paleontologic markers of this lineage are pelves compatible with bipedality and braincase size. |
|
This strengthened the skull and protected the braincase. |
|
Three age classes were assigned on the basis of ventral braincase suture closures between the basioccipital and basisphenoid, and between the basisphenoid and presphenoid. |
|
Baird and Olsen's report of a dicynodont therapsid was based on the partial braincase reidentified here as that of a paracrocodylomorph pseudosuchian. |
|
On display is half of a Diplodocus braincase, which provides scientists a number of important clues about the large-scale brain structure of this extinct dinosaur. |
