Creatures that live in forests and other types of forestal places during the Maastrichtian are featured.
Recurring tropes are:
The Austroposeidon segment provides examples of:
- Stock Animal Behavior: One of the rare cases when this show plays this straight — the Austroposeidon are shown grazing from treetops and knocking down trees, which is their typical behaviour in modern media after Aquatic Sauropods got discredited.
The Triceratops segment provides examples of:
- Eat Dirt, Cheap: The Triceratops enter a cave to feed on clay, which helps them digest the toxic plants they eat.
The Carnotaurus segment provides examples of:
- Did Not Get the Girl: Despite his spectacular mating dance, the male Carnotaurus gets rejected by the female.
The Qianzhousaurus and Corythoraptor segment provides examples of:
- Noisy Nature: Averted — unlike tyrannosaurs in most dinosaur media, the Qianzhousaurus is completely silent when it ambushes the Corythoraptor flock.
- Terrifying Tyrannosaur: The Qianzhousaurus is depicted as a stealthy predator that stalks its prey.
The North American forest fire segment provides examples of:
The young Therizinosaurus trio segment provides examples of:
- Fantastic Fauna Counterpart: As a large forest-dweller with massive claws, a shaggy coat and an appetite for honey, the Therizinosaurus brings a bear to mind.
- Goofy Feathered Dinosaur: The young Therizinosaurus are inexperienced and clumsy in their attempts to get some honey from a beehive, providing most of the comedy from the segment. The adult that appears later and easily takes down the beehive is portrayed in a much more majestic and respectable light, however.
The Hateg Island segment provides examples of:
- Book Ends: The first season ends with the Hatzegopteryx flying towards the sea after launching himself from a beach, in a similar way of how the 'Coasts' episode began with the footprint of the father T. rex in the sand when he decided to cross the Western Interior Seaway.
- Eats Babies: The Hatzegopteryx gobbles up a baby Zalmoxes.
- Giant Flyer: The Hatzegopteryx is the largest animal to ever fly (shorter than Quetzalcoatlus but heavier than it), and the final scene of the season shows him flying from Hateg Island towards a new feeding ground in a really magnificent way.
- Riding into the Sunset: Or "flying into the sunset" in this case. The first season of "Prehistoric Planet" ends with the Hatzegopteryx flying towards new lands while leaving Hateg Island behind, with the sunset sun clearly seen in the background.
