Spinosaurus mirabilis

Part of the APEX PREDATORS Exhibit

Late Cretaceous Period, approx. 100-94 million years ago

1:5 Scale Skull Replica

SPECIMEN PROFILE

Spinosaurus mirabilis is interpreted as a distinct regional variant within the Spinosaurus lineage from North Africa, recovered from slightly different stratigraphic layers than more commonly referenced specimens. It retains the core semi-aquatic adaptations associated with the genus, but exhibits subtle anatomical differences that suggest variation in skull robustness and neural spine structure.

Compared to more derived Spinosaurus forms, S. mirabilis appears to reflect a slightly less specialized stage of aquatic adaptation, with skeletal proportions that suggest a greater degree of terrestrial mobility. Its morphology indicates a flexible predator capable of exploiting both riverine hunting grounds and adjacent floodplain environments, rather than being fully committed to a fish-dominated niche.

COLLECTOR & CURATOR NOTE

A rare and structurally distinct Spinosaurus lineage variant—offering insight into the evolutionary experimentation that shaped one of the most unusual predatory dinosaurs ever discovered.

CONSTRUCTION & DISPLAY
