Spinosaurus is known to have eaten fish and small to medium terrestrial prey as well. [5] Evidence suggests that it was semiaquatic; how capable it was of swimming has been strongly contested. Spinosaurus's leg bones had osteosclerosis (high bone density), allowing for better buoyancy control.
Spinosauridae (or spinosaurids) is a clade or family of tetanuran theropod dinosaurs comprising ten to seventeen known genera.Spinosaurid fossils have been recovered worldwide, including Africa, Europe, South America and Asia.
As accurate osteologically as that reference is, it unfortunately skinwraps the animal. The neck needs to be a smooth and unbroken transition into the body, making it effectively impossible to point out where the head goes into the neck and the neck goes into the body. This fossil is a good reference. Luxquine 23:30, 28 February 2022 (UTC)
The authors also proposed Spinosaurus maroccanus as a junior synonym of Sigilmassasaurus, and rejected the proposal of a Spinosaurus aegyptiacus neotype. [4] A study by British paleontologist Thomas Arden and colleagues in 2018 concluded that Sigilmassasaurus was a valid genus and formed a tribe with Spinosaurus termed Spinosaurini.
