Majungasaurus (/ m ə ˌ dʒ ʌ ŋ ɡ ə ˈ s ɔː r ə s /; lit. ' Mahajanga lizard ') is a genus of abelisaurid theropod dinosaur that lived in Madagascar from 70 to 66 million years ago, at the end of the Cretaceous Period, making it one of the last-known non-avian dinosaurs that went extinct during the Cretaceous–Paleogene extinction event.
In Carnotaurus, this opening was higher than long, while it was longer than high in related forms such as Skorpiovenator and Majungasaurus. The antorbital fenestra was bounded by a larger depression, the antorbital fossa , which was formed by recessed parts of the maxilla in front and the lacrimal behind.
Data for the abelisaurid fore limbs are known from Eoabelisaurus and the carnotaurines Aucasaurus, Carnotaurus, and Majungasaurus. All had small fore limbs, which seem to have been vestigial. [11] The bones of the forearm (radius and ulna) were extremely short, only 25% of the length of the upper arm in Carnotaurus and 33% in Aucasaurus. The ...

There are two principal types of bones: Dermal bone is directly formed in the dermis (skin), usually growing from initially thin plates. Among others, most bones forming the outer surface of the skull and lower jaws are dermal bones. In contrast, endochondral bone is formed from a cartilaginous precursor, which ossifies (turn into bone). [1 ...
