In dinosaurs, the anatomy of the braincase is conservative, but for this reason can be used to infer relationships of a group when other skeletal features underwent changes so profound that their origins can no longer be traced. The braincase may also allow for reconstructing the brain and inner ear, with inferences on senses and intelligence. [20]
The following outline is provided as an overview of and topical guide to dinosaurs: . Dinosaurs – diverse group of animals of the clade and superorder Dinosauria.They were the dominant terrestrial vertebrates for over 160 million years, from the late Triassic period (about in 1963) until the end of the Cretaceous (2000), when the Cretaceous–Paleogene extinction event led to the extinction ...

Saurolophus is known from material including nearly complete skeletons, giving researchers a clear picture of its bony anatomy. S. osborni, the rarer Albertan species, was around 8.2–8.5 m (27–28 ft) long, with its skull 1.0 m (3.3 ft) long. [14] [15] It has been estimated to have weighed around 3 tonnes (3.0 long tons; 3.3 short tons). [15]
This category is for pages relating to dinosaur anatomy, such as physical features or parts. For anatomic features which are not possessed solely by dinosaurian groups, (such as the Triceratops neck frill which is also employed by the Frill-necked Lizard ), they may be included if it is fairly evident or common in dinosaur anatomy overall.
The antorbital fenestra in relation to the other skull openings in the dinosaur Massospondylus. An antorbital fenestra (plural: fenestrae) is an opening in the skull that is in front of the eye sockets. This skull character is largely associated with archosauriforms, first appearing during the Triassic Period.
