The skull of Spinosaurus was long, low, and narrow, similar to that of a modern crocodilian, and bore straight conical teeth with no serrations. It would have had large, robust forelimbs bearing three-fingered hands, with an enlarged claw on the first digit.

2025年1月16日 · Like other spinosaurids, Spinosaurus possessed a long narrow skull resembling that of a crocodile and nostrils near the eyes, instead of near the end of the snout. Its teeth were straight and conical, instead of curved and bladelike as in other theropods. All these features are adaptations for piscivory (that is, the consumption of fish).

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. Their remains have generally been attributed to the Early to Mid Cretaceous. Spinosaurids were large bipedal carnivores.

In art, the Spinosaurus may be depicted as bipedal or quadrupedal depending on the date of the work. The dorsal spines most often form a fin on the creature’s back, and its head is long and narrow, resembling that of a crocodile. Quick facts about Spinosaurus: All the Spinosaurus illustrations below were collected from the internet.

It is also one of the first dinosaurs to have been identified as the first possible “swimming dinosaur”. Another interesting fact is that the Spinosaurus has a six foot long skull that was shaped much like a modern crocodiles skull. This made it easier for this dinosaur to fish.
