|The largest dinosaur predator that ever stalked Earth was also the strangest. Spinosaurus aegyptiacus was the largest carnivore dinosaur of all time. It measured 18 meters (50 feet) long, 4.9 to 7.7 meters (16 to 25 feet) tall and 12 tons. Spinosaurus lived in Cretaceous North Africa from 102 to 93 mya|
|In November 2014 scientists announced the discovery in Moroccan desert cliffs of new fossil remains of Spinosaurus aegyptiacus, a monster that breaks the mold for how a dinosaur predator looked and behaved.|
It was roughly 2.5 metres longer than Tyrannosaurus rex and equally massive. Living during the Cretaceous Period, Spinosaurus is the only known carnivorous dinosaur adapted for a semi-aquatic lifestyle.
The distinctive spines of Spinosaurus, which were long extensions of the vertebrae, grew to at least 1.65 meters (5.4 ft) long and were likely to have had skin connecting them.
|Spinosaurus roamed the swamps of what is now North Africa.|
Spinosaurus terrorized a vast North African river system from Morocco to Egypt. Spinosaurus's environment was "the most dangerous place in the history of our planet."
Spinosaurus was the undisputed king of waterways teeming with sharks and 11-metre crocodilians. Flying reptiles with wingspans of seven meters soared overhead. It may not have been very agile on land but would have taken down anything unfortunate enough to be in it's path.
