Skull length was estimated at 85 centimetres (33 + 1 ⁄ 2 in) in 1985. The skull is relatively deep. The skull is relatively deep. Although there are no bony crests or horns, like those found in some other abelisaurids, such as Carnotaurus , rough ridges on the snout and above the eyes might have supported some kind of crest made out of ...

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 ...
With the skull as the holotype specimen, they were grouped into a new genus and species as Sahelanthropus tchadensis, the genus name referring to the Sahel, and the species name to Chad. These, along with Australopithecus bahrelghazali , were the first discoveries of any fossil African great ape (outside the genus Homo ) made beyond eastern and ...
The skull of the Harvard skeleton is estimated to be 2.85 metres (9.4 ft) long. [78] [g] The cranial measurements of the last three specimens previously cited surpass in size the skull of any known theropod dinosaurs. [81] The snout and the mandibular rostrum are long and narrow in shape. [63]
In the latter work, which examines the subject of paleoanthropology, Bouts developed a teleological and orthogenetical view on a perfecting evolution, from the paleo-encephalical skull shapes of prehistoric man, which he considered still prevalent in criminals and savages, towards a higher form of mankind, thus perpetuating phrenology's ...
The skull is much narrower than long, [7] reaching its greatest width just behind the eyes (the postorbital bar). [8] The anterior portion is "bluntly triangular". [8] In lateral view, the skull reaches its highest point at the rear of the skull table. [9] "The external nostrils overlie the internal nares". [8]
Neurons connect to form neural pathways, neural circuits, and elaborate network systems. The whole circuitry is driven by the process of neurotransmission. The brain is protected by the skull, suspended in cerebrospinal fluid, and isolated from the bloodstream by the blood–brain barrier.
