In the Cretaceous seaway, the plesiosaurs majestically flew through the water. The mighty elasmosaurs moved with a grace that one would not expect from a giant sea reptile, making it all the more amazing to witness. As for the smaller polycotylid with them, the Doly cut through the water like a dolphin, at times swimming circles around its giant cousins. Occasionally, a fish would disappear down the gullet of one of the sea creatures, either caught by surprise as an elasmosaur suddenly turned toward it or snatched by the accelerating polycotylid, moving in a burst of lightning speed.

Above, the team watched all of this on the R.O.V., impressed with the beauty of the prehistoric reptiles and how calm they were.

"Sorry to offend you," began Elise, "but Sea Monsters has nothing on this!"

"None taken," responded Nigel. "This is just amazing, isn't it?"

"True...hey, what's that?" asked Elise.

Turning their collective attention back to the screen, the team was surpised to notice that another creature had appeared. It was brownish grey in color, and roughly the size of the polycotylid, but far more streamlined.

Other than its size, though, the creature would've easily fit in the modern ocean.

"Is that a nurse shark?" asked Violet.

"Most likely Ptychodus," answered Aileen.

While marine reptiles were the most famous creatures in the Mesozoic Seas, sharks also did quite well during this time, with many modern forms beginning to appear. Among them were nurse sharks, goblin sharks, and even great white-esque sharks.

And while the Ptychodus are not the targets of this mission, it would make an excellent addition to the park.

It doesn't take the team long to decide to go after the giant nurse shark. The team decides to split in half: Nigel, Sean, Elise, and Tristan suit up to enter the ocean, while Tai, Violet, Aileen and Aiden stay aboard the ship, to keep watch for the rest of the team. In a matter of moments, the rescue team is beneath the waves, leaving the younger recruits to tend to the Mariner.

"Well, I guess we wait," remarks Tai.

"Yep," notes Aileen. "...This is gonna be boring."

CAW!

"...I Stand corrected."

Back at the park, Bob is once again dealing with the park's ceratopsians. This time, it's the Torosaurus.

Near Triceratops Creek, Bob peers through a fence, finding himself face to face with one of the Torosaurus, though only for a moment before the horned dinosaur tries to break down the fence. While not near enough to the giant herbivore to be in danger, Bob still flinches at the sight of the mock charge.

"I don't know what up with her. Suzanne told me this one's a female, so she this isn't over mates, and there's plenty enough food in their exhibits. I haven't seen her building a nest, so pregnancy isn't the problem here. Suzanne's finally got some time away from her giant amphibians, so she's going to come over and help me, but until then, all I can do is watch."

A grunt from the ceratopsid unnerves Bob, who quickly back up to one of the park's jeeps. For the moment, avoiding conflict is the best.

Back in Prehistoric Arizona, Nigel and co are on the trail of the giant nurse shark.

The team has descended beneath the plesiosaurs, as the shark has made its way toward the ocean floor. While mostly barren, a couple of clams and mussels eek out a living her, and it is this the shark is after.

"This shark's just like it's modern relatives," notes Nigel. "Nurse sharks are normally durophagous; while they eat fish, they can also eat hard shelled creatures likes bivalves. This one must be after the clams on the ocean floor.

Then, to Nigel's surprise, a second Ptychodus descends toward a nearby set of clams.

It appears that this shark is not alone.

Soon a third shark appears, and then another, and another, until eight sharks are cruising over the ocean floor, looking for clams to eat.

Sensing an easy opportunity for a rescue, the team begins to set up portal beacons on some loose outcropping containing several truly gigantic bivalves. A couple of fish had taken shelter among them, allowing them to bring back multiple species for the price of two. At first, the sharks kept their distance form the humans, but once their fear of the new creatures subsided, they were willing to advance on the new swimmers. This was exactly what the team wanted as it brought them close to the portal beacons. When the shark's turned their attention from the humans to the giant mollusks, the team activated the portal grenades, sending the mollusks, their passengers, and the sharks into the present.

"Well, that was easy," noted Elise.

Her mood soon darkened, though, when a shadow fell over her. Looking up, she found that, to her surprise, it was from another shark. This one, though, has a very pointy snout.

The rest of the team quickly noticed her change in mood and also stared up.

"Is that a...goblin shark?" asked Sean.

"Looks like one," noted Tristan, "but there are a bunch of sharks that looked like that during the Cretaceous, and I'm not really sure which type this one is."

"Well, it's not alone," noted Nigel.

In fact, well over a dozen of these sharks were swimming above them along with various other types of shark, attracted to a large school of fish. Said school has merged with the one the plesiosaurs were following, causing the various predators to unite in search of food.

"Didn't expect the sharks to join up with those plesiosaurs and not try to take a bite out of them," noted Sean.

"Me neither," remarked Elise, "but we should still follow them. Maybe the sharks will lead us to the turtle? I mean, some sharks eat turtles."

"Can't argue there," remarked Tristan.

"Let's go!" was Nigel's reply.

With that, the underwater team began to pursue the unusual animal alliance, hoping perhaps that it would lead them to their quarry.
