New 'Hell Heron' Dinosaur Discovered in Sahara: Spinosaurus mirabilis Ruled Africa 95 Million Years Ago

• Paleontologists unearthed a new Spinosaurus species, Spinosaurus mirabilis, in the Sahara Desert, dating back 95 million years.
• Named for its "astonishing spine lizard" crest, S. mirabilis was a 12-meter, 7-tonne carnivore with an elongated snout and longer hind limbs.
• Dubbed a "hell heron," it specialized in wading in shallow waters to hunt fish, using backward-positioned nostrils and interlocking teeth.
• Its distinctive 20-inch scimitar-like crest was likely a visual signal for mating or warding off rivals, not a weapon.
• The inland discovery challenges the theory of Spinosaurus as a fully aquatic ocean predator, confirming its semi-aquatic wader status in river systems.
