Spinosaurus aegyptiacus

Part of the APEX PREDATORS Exhibit

Late Cretaceous Period, approx. 99-93 million years ago

1:5 Scale Skull Replica

SPECIMEN PROFILE

Spinosaurus aegypticus was one of the most unusual large theropods ever discovered, inhabiting river-dominated ecosystems in what is now North Africa. Unlike most large predatory dinosaurs, it was highly adapted to a semi-aquatic lifestyle.

Its elongated skull, conical teeth, and paddle-like tail suggest a diet heavily focused on fish and aquatic prey, while still allowing opportunistic hunting of terrestrial animals. The iconic sail along its back—formed by elongated neural spines—likely played a role in display, thermoregulation, or both. Spinosaurus represents a rare evolutionary shift among large theropods toward water-based predation.

COLLECTOR & CURATOR NOTE

A river-dwelling apex predator unlike any other theropod—its sail-backed silhouette and aquatic adaptations mark a radical departure from traditional land-based carnivores.
