Spinosaurus

Spinosaurus aegyptiacus

The largest known predatory dinosaur, Spinosaurus aegyptiacus exceeded even Tyrannosaurus in length at around 15 meters and near 7,400 kilograms. A tall sail of elongated spines, reaching about 1.8 meters, rose along its back. Its long, narrow, crocodile-like jaws and recent skeletal discoveries point to a semi-aquatic life spent hunting fish in river systems during the Early Cretaceous, roughly 145 to 100 million years ago. Ernst Stromer described this piscivore in 1912 from the Bahariya Oasis of Egypt, though much of the original material was destroyed during the Second World War, leaving the reconstruction of its full anatomy a continuing scientific challenge.

Spinosaurus is the largest known predatory dinosaur, even bigger than T. rex. Its distinctive sail-like structure on its back could reach 1.8 meters tall. Recent discoveries suggest it was semi-aquatic, adapted for hunting fish in rivers.

Diet & Feeding

Piscivore

Spinosaurus was a fish-eating dinosaur. Piscivores typically lived near water sources and had specialized adaptations such as elongated snouts and conical teeth for catching fish.

Time Period

Cretaceous Early Mesozoic Era

Spinosaurus lived during the Cretaceous Early period of the Mesozoic Era, approximately 145,0 to 100,5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
