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]

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]
Skeletal diagram showing known remains of the holotype and a referred specimen. The first fossil specimen of the dinosaur later named Sinosauropteryx prima was uncovered in August 1996 by Li Yumin. Yumin was a farmer and part-time fossil hunter who often prospected around Liaoning Province to acquire fossils to sell to individuals and museums.
The uncinate processes are the small white spurs about halfway along the ribs. The rest of this diagram shows the air sacs and other parts of a bird's respiratory system:1 cervical air sac, 2 clavicular air sac, 3 cranial thoracal air sac, 4 caudal thoracal air sac, 5 abdominal air sac (5' diverticulus into pelvic girdle), 6 lung, 7 trachea
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 ...
Masiakasaurus is a genus of small predatory noasaurid theropod dinosaurs from the Late Cretaceous of Madagascar. In Malagasy, masiaka means "vicious"; thus, the genus name means "vicious lizard". The type species, Masiakasaurus knopfleri, was named after the musician Mark Knopfler, whose music inspired the expedition crew.
