There is something missing from our world. The amazing creatures that time has left behind. But what if we could bring them back?

What if extinction didn't have to be forever?

We're going back in time on a safari with a difference as wildlife adventurer Nigel Marvin plunges into prehistory to rescue creatures on the brink of extinction. His plan is to bring them back to the safety of the present and give them a second chance.

This time, Nigel returns to Prehistoric Scotland alongside a fellow .

Welcome to the ultimate wildlife sanctuary.

Welcome to Prehistoric Park.

With the aftermath of the recent incident on the far side of the mountains mostly handled, Nigel is once again looking at potential rescue targets. This time, though, the target in question is quite a bit smaller than normal.

At his den once more, Nigel is looking over the photos he had been examining during the incident a week prior - pictures showing a massive river dwelling fish, with a wicked set of teeth.

This creature is Rhizodus, the apex predator of its time.

"This fish was once called the ultimate river monster. When it was around, there was nothing able to compete with it for dominance - even giant amphibians were second to this beast. I would love to bring a few of these back to the park, and today, I'm going to join the man who gave this fish its moniker in trying to catch some.

The man Nigel is referring to is Jeremy Wade, host of the show River Monsters, as well as a professional angler and biologist. While most of his career has been focused upon the preservation of existing riparian predators on the edge of extinction, this is the one exception he's willing to make for an extinct species.

Of course, that doesn't mean he isn't impressed with the park's already prodigious number of rescues - especially some of the odder ones.

(AN: Apologies for the sudden shift in narration - I'm just a big fan of how Jeremy Wade narrates his own series)

I am Jeremy Wade. For years, I've traveled all over the world, investigating incidents where people have been killed by an assortment of river monsters. Crocodilians, piranhas, giant catfish, and sharks are just some of the creatures I've investigated.

Today, however, I am facing what is possibly the strangest of all my inquiries - a chance to rescue a prehistoric river monster. The zoologist Nigel Marven has invited me on what he calls a safari with a difference to rescue prehistoric species, and today, he plans to save the greatest prehistoric river monster, Rhizodus.

Odd as the request may be, this is one opportunity I refuse to pass up.

What I see when I arrive is more than enough to assure me that this request is genuine.

Sitting atop a log, Wade is watching the riverbank in front of him. Resting on the sand bar is a huge crocodilian - not the biggest at the park, but still larger than any specimen today. Its elongated snout is opened in a yawn of sorts, with a trio of birds working to clean its snout. Nearby, an armored dinosaur digs into a bush, occasionally glancing at the predator, while in a separate stream, a group of eurypterids flees from a surfacing mosasaur. Completing the odd scene is a ground sloth, browsing without a care, while beside it is a Triceratops.

Despite seeing so many spectacular creatures in his many adventures, Wade is clearly amazed with what he is watching.

"I really can't believe it - I'm literally within spitting distance of a dinosaur, as well as several prehistoric river monsters. This creature in front of me isn't the most obvious of prehistoric crocodilians - it's body shape matches up with Sarcosuchus, but the end of the snout is too narrow. It's the Triceratops that let me figure this out - this predator treats all of the other dinosaurs I've seen here with suspicion, including several sauropods, but it seems at ease around the Triceratops and the armored dinosaur. There's only one crocodilian of this size known from the same fossil sites as Triceratops, so this creature must be a Thoracosaurus, which in turn means that the armored dinosaur is Denversaurus.

The behavior of these creatures is too fluid to be any form of puppetry - these are real animals. It seems that Mr. Marven has indeed cracked the secret of time travel, or at least had help with that.

Without warning, a large amphibian suddenly surfaces and makes a mad dash into a nearby pond, which Wade observes with shock. Said shock only grows when a ground sloth suddenly emerges from the riverbank and starts browsing on a nearby tree.

"Sorry about that," intones a familiar voice. Turning to his right, Wade finds Nigel making his way toward the riverbank, careful to avoid provoking the ground sloth.

"Sorry I couldn't give you a proper welcome here, I just needed some time to make sure the portal would lead us to our target."

Wade is more than understanding. "No problem. I have to admit, this is the last thing I expected to see - I've faced all kinds of river monsters, but never any that were truly extinct."

"We'll see how long that lasts."

While Nigel and Jeremy prepare to rescue the ultimate river monster, the rest of the away team has other business to attend to - Nigel wants to run this mission with just himself, the camera crew, and his guest, so everyone else is busy working on other projects.

"So, why are we walking through these mountains again, Elise?"

The girl in question turned toward Lucas. "Because we need to document all the potential oddities caused by that...portal storm...that happened a few days ago."

Lucas took a look around.

"...You mean like how these mountains now look like a coral reef?"

Elise opened her mouth answer, only for her attention to be caught by a jellyfish flying through the air. Somehow.

"...Yeah."

Lucas opened his mouth to answer again, only for a loud crunch to turn the duo's attention toward a giant clam shell. There, a Carnufex was busy gorging itself on the sessile organism.

Lucas finally regained control of his vocal chords. "This is gonna be a long day."

"No shit."
