In the lands of Montana and South Dakota, a female T-Rex had gone on a hunt, while her mate stayed behind to guard the nest, to help the Tarbosaurus family protect the hatchlings that are playing about.

Traveling in search of prey, the adult female Tyrannosaurus could be gone by then. She continued her journey, in the search for something to eat.

The male T-Rex was watching vigilantly over his offspring, alongside the Tarbosaurus family, who was also watching over theirs.

Just then, a predatory Nanotyrannus had decided to challenge the much stronger and larger Tyrannosaurus. Which was the biggest mistake.

The T-Rex took notice right away, opening his jaws as the smaller but more agile dinosaur lunges at his face, hoping to get a bite at one of his eye sockets, but instead met his timely painfully, slow end as the male Tyrannosaurus clamps his jaws down, with full force. Crushing his opponent, and crippling him with enough force to slow down the smaller adversary as the Nanotyrannus got back up.

Elsewhere, the female has chosen her first victim: a slow, lumbering Triceratops. She knew that one wrong move could very well end her life, so she waited, and waited for her target to approach, and that's when she will strike.

All the Tyrannosaurus cares about is getting his teeth on his prey. Once he's got you, you're done. Game over.

The bite force of a T-Rex can measure up to 3,000 to 8,000 pounds per square inch. Some estimates say 12,800 pounds.

That's stronger than the jaws of an alligator or today's lion.

As the sick Triceratops got closer to it's would be killer was hiding, it began to graze peacefully on it's food, until sensing that there was danger nearby.

The female T-Rex, individually known as 'Rexy,' was quietly waiting from behind the foliage.

As the herbivore turned around, searching for wherever the danger might be, the female then quietly stalks her prey, remaining undetected, as much as possible, then goes for the kill, biting it's neck.

The Triceratops struggled and bellowed in excruciating pain, trying to shudder and shift to loosen the T-Rex's grip on it's neck. But the female will not release her prey.

Once the herbivore was finally down, after 5 more seconds, the female looked around to make sure no one was around, before dragging her prey back to her territory shared with her mate.

Meanwhile, at the nest-

The injured and mortally wounded Nanotyrannus was desperately trying to get at his opponent's offspring and kill them, but it didn't work, as the male, fueled by rage amd adrenaline, brutally smacks the body of his smaller adversary, and sending him flying, a few feet away to a nearby rock, severely injuring the Nanotyrannus and almost putting it out of commission.

And as the injured Nanotyrannus got up and tried again, even though he is fighting a losing battle. He would not stand a chance against a full grown T-Rex. Until the ground began to vibrate. It's a sound that can be heard for miles away. It's the sound of the female T-Rex, who had just come back from a hunt, with a carcass dangling in her mouth.

The female stares at the injured adversary, then turning to look at her mate. Her mate rumbled utterly.

The female then began to drop the carcass and grabs the heavily bleeding Nanotyrannus, and exerts a bite force of 8,000 PSI to 12,799 PSI. She crushes the back, crushes the ribs, and ends the life of this intruder, making short work of him as her mate watched.

Letting go of the dead dinosaur, Rexy then began using her massive foot claw, cutting the neck of the Nanotyrannus, ripping him apart.

Having killed the attacker, she turns her attention to her family, even her mate, who signals the hatchlings that it's safe now, and that it's time to eat.

And by then, the Tyrannosaurus family had some peace and quiet for a while now. Or so it seemed......

Up ahead, a familiar Spinosaurus growled with revenge, staring eerily at his arch rival.

"We shall meet again, old tyrant. For I am reborn!" Declared a vengeful Shredder, who was reborn from the original as he stomped off.

The Nanotyrannus was just a distraction for the real thing that lies in wait. A prelude to the main event. That will inevitably arise. In the months to come.
