Setting One : The Hell Creek Formation

A herd of Alamosaurus is seen trudging through a lake; a few go around it to get some leaves from a nearby tree. Some Pteranodons are seen eating some pieces of an unlucky juvenile Mosasaur with some Archeoraptors taking several pieces when the Pterosaurs aren't looking.

Some large shadows appear. It is four Quetzalcoatlus. As they all land, the Pterosaurs fly away and Dromeosaurids scatter swiftly. It's better to retreat since they are easy pickings for these large Azdarchids.

A group of Pteranodons is seen nesting. One male is seen with a nesting female. While another individual is seen diving to get fish for its young.

Some Ankylosaurus are seen drinking from a watering hole, with some Denversaurus joining them. A herd of Triceratops and Torosaurus are seen crossing this same river in the distance.

Far away from the riverbank, we see an Anzu protecting its eggs in a nest. As it sits a small mammal comes close, but the feathered Oviraptorid lets out a hiss to scare it off. As the small mammal scurries off, this feathered dinosaur continues to incubate its eggs.

Setting 2: Somewhere further away

A juvenile tyrannosaurid is seen cleaning the teeth of a theropod (not fully shown).

Some nearby Ornithomimus and Struthiomimus flee the area upon sensing something large in the distance. They began to flee. Some Edmontosaurus see this and alert their herd. They move out of the area.

A Tyrannosaurus Rex with a few injuries from its past encounters.

It challenges this other theropod for a carcass.

The two carnivores size each other up by circling each other.

The other theropod strikes first. It manages to land a devastating bite on the Tyrannosaurus' tail. It rips a chunk from its tail. But the T Rex managed to bite the back of the other theropod.

The other theropod roars in pain. This fight is not worth it. It leaves.

One walks away and the other eats a meal. A mosquito lands on the T. rex's large open wound. This insect then lands on a tree branch.

Now, if you're wondering why I did not name or describe the other theropod. It's because I want to keep it vague and mysterious. You would only get to see parts of it but never the full thing only a few shots, but not the full thing. Was it another T. rex or something else? You decide.
