This single known fossil of Abelisaurus consists of a skull, lacking the lower jaws, that is incomplete, especially on the right side. Most of the connections between the snout and the back of the skull are absent. It is also missing most of the palate (roof of the mouth). Despite the missing pieces, it could be estimated at over 85 centimetres ...
In the skull, a supratemporal fossa (excavation) is present in front of the supratemporal fenestra, the main opening in the rear skull roof; Epipophyses, obliquely backward-pointing processes on the rear top corners of the anterior (front) neck vertebrae behind the atlas and axis, the first two neck vertebrae
To support its large dentition, the jaws of megalodon would have been more massive, stouter, and more strongly developed than those of the great white, which possesses a comparatively gracile dentition. Its chondrocranium, the cartilaginous skull, would have had a blockier and more robust appearance than that of the great white. Its fins were ...
The foramen ovale is used as the entry point into the skull when conducting a Percutaneous Rhizotomy using either radio-frequency ablation, balloon compression or glycerol injection. These are performed to treat trigeminal neuralgia. In the procedure, the electrode is introduced through the cheek of an anesthetized patient and radiologically ...
Since the skull ossifies over the brain during infant development, external craniological means could be used to diagnose the internal states of the mental characters Through careful observation and extensive experimentation, Gall believed he had established a relationship between aspects of character, called faculties , with precise organs in ...
[264] [265] As brain size increased, this altered the size and shape of the skull, [266] from about 600 cm 3 in Homo habilis to an average of about 1520 cm 3 in Homo neanderthalensis. [267] Differences in DNA, gene expression, and gene–environment interactions help explain the differences between the function of the human brain and other ...
