For a very long time, it was believed that the Tyrannosaurus Rex, king of the dinosaurs, one that everyone knows about and loved, was the largest predatory dinosaur to step foot on the face of the Earth. That was then.. until a new predator, has arrived on the scene, it had jaws, evolved to grip prey, rather than tear off flesh, strong, powerful arms and claws, and a body with a sail that made the creature much bigger and taller than the T-Rex. Enter... Spinosaurus Aegypticus.

As the Spinosaurus attacked the mostly destroyed plane, in an attempt to reach down and pluck one of the humans, all hurled up inside and crawled safely away to avoid being eaten, the man in gold, was none other, than Alan Grant.

"Follow me! This way!" He yelled, as they all ran away from the monstrous titan, who roared and followed suit, with Udesky, running behind the group.

"In here!" Alan yelled, as they all made a run for cover behind the trees, as the menacing Spinosaurus continued to chase them, roaring loudly, only to be blocked by a giant tree, struggling, and defeated, the Spinosaurus let out a loud roar, as the humans escaped the monster, running for cover before slowing down to a stop.

"I think we lost him." Alan said, before turning around, only to encounter a giant carcass, of what appears to be a dead Parasaurolophus, with flies buzzing around him.

"It's okay, it's dead."

A large, rounded head revealed itself in the form of the Tyrannosaurus Rex, it's head rising, filled to the top and bottom, being mottled with blood and carrion, from the carcass.

"Nobody, move a muscle."

Obeying, the group freezes for a few seconds, until the T-Rex roars loudly, to scare them away, which then they took off running, Alan running from behind.

The Tyrannosaurus gave chase immediately, chasing them, making them head back the way they came. Only to come face to face with-

THE FIRST MONSTER.

We now get our first full unobstructed view of the gigantic creature, SPINOSAURUS AEGYPTICUS. Over forty feet long and twenty-five feet high, the dinosaur has a bony sail along its back. Its head is crocodilian with rows of long, curving teeth. Sinewy six foot arms terminate in three fingers hands with fourteen inch claws.

Nowhere else to run, the group scatters into the brush as the two behemoth predators, T-Rex and Spinosaurus, rush forward, their ROARS thunderous.

Paul and Amanda scramble into one direction, Billy and Udesky in the other.

But Grant can't go anywhere - his foot is stuck between two branches. He manages to free himself as the two dinosaurs approach.

They'll have to deal with each other before eating the humans.

Grant dives down between two fallen trees as the Spinosaurus and T- Rex circle one another like gladiators, each searching for the other's weakness.

Laying flat on his back, Grant lets out a terrified GASP as the giant foot of Spinosaurus lands across the two trunks mere inches from his face.

Spinosaurus lunges forward, powerful jaw open wide.

The T-Rex sidesteps the assault, its tail knocking down small trees as it spins out of the way.

In the tress, Paul and Amanda scurry again for cover.

Between the fallen trunks, Grant attempts to get away on his hands and knees.

T-Rex presses the attack, slamming its tail into the flank of its adversary. Spinosaurus is knocked back, and Grant is again forced to duck for cover.

As Spinosaurus struggles to regain its balance, T-Rex dives forward. Spinosaurus is driven backwards as T-Rex tries to grip its throat.

Amanda yanks Paul out of their path. They scramble over to Billy.

Now on its side, Spinosaurus fights back ferociously. It slashes at T-Rex with its long arms and razor sharp claws, then finally kicks the animal with one mammoth foot.

Tyrannosaurus staggers back, wounded.

Down below, Grant is splashed by the blood pouring from the dinosaur, as he slowly makes his way towards his fellow humans.

Spinosaurus lunges for the T-rex with gaping jaws and manages to topple T-Rex off its feet and sends the falling dinosaur to the ground.

With an earth-shuttering CRASH, the dinosaur lands between Grant and the rest of the group.

The companions scurry out of the way, but as they do so, the head of the T-Rex now lands almost directly on top of them.

Plastered against an immense tree, the group watches in horror as T-Rex starts to rise but is thrown back down as Spinosaurus latches onto its throat. Spinosaurus crushes the life out of its adversary, and T-Rex opens and closes its jaw a mere inches from our terrified friends.

Finally, Grant reaches the others.

"Come on!" Grant yelled as the Rex got it's life choked the hell of it from the jaws of the Spinosaurus, the tyrant lizard gets up and rams the larger behemoth, bites the neck of the Spinosaurus, struggling to keep a tight grip.

The Spinosaurus fights back even more aggressively and grips his teeth and jaws into the neck of the Tyrannosaurus, snapping it's neck, and knocking it's dead body to the ground.

Spinosaurus lets out a victorious roar, and the blood-drenched paleontologist, leads the group through the undergrowth.
