Size and Weight: Spinosaurus is considered one of the largest known carnivorous dinosaurs, possibly exceeding T. rex in length, with estimates suggesting it could reach up to 50 feet (15 meters) in length and weigh around 7 to 10 tons (6,400 to 9,000 kilograms).
-
Unique Features: It had a distinctive sail-like structure on its back formed by elongated neural spines, which could have been used for display, thermoregulation, or storage of fat.
-
Aquatic Adaptations: Spinosaurus is thought to have been semi-aquatic, with adaptations such as a long, crocodile-like snout and conical teeth suited for catching fish. Its limb proportions and possibly its tail suggest it spent significant time in water.
-
Time Period: Spinosaurus lived during the mid-Cretaceous period, approximately 112 to 93 million years ago, in what is now North Africa.
-
Diet: Unlike many other large theropods, Spinosaurus likely had a diet primarily consisting of fish, as indicated by its specialized teeth and the discovery of fish remains in its fossilized stomach contents.
