The holotype of this species is USNM 10300, a partial skull from the Late Miocene Monterey Formation of Lompoc, California. [3] Although previously included in the same genus as the humpback whale, "M." miocaena differs in having a less ventrally inflated tympanic bulla, short and rectangular nasals, and the narrow finger of the frontal is excluded from the posterior part of the nasal bones.
The holotype of this species is CASG 1733, a partial skull from the Late Miocene Monterey Formation of Saucito Rancho, California. [2] In their description of Parabalaenoptera, Zeigler et al. (1997) assigned B. ryani to Cetotheriidae, [3] but a recent overview of fossil balaenopterid taxa considers it a distinct genus of balaenopterid based on a unique combination of primitive and derived ...
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 ...
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 ...

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]
