A week after the successful rescue of the Brachiosaurus and various other Jurassic Morrison Formation wildlife, Drew sets off to the Lourinha Formation alongside Leon and Adrian to rescue Compsognathus. In the process, Leon finds himself wondering if he truly has what it takes to be a keeper and rescue team member for Prehistoric Park. Meanwhile, back at the park, life is unfolding smoothly for the staff and the animals currently already rescued, but not without a few tiny hints of potential drama and issues to come.
- Abusive Parents: Cass and Tina's parents prove to be the emotional variant of this, as they did nothing to discourage the divide that ensued between their two daughters and even openly pit them against each other while always favoring Tina.
- A Day in the Limelight: Intended to serve as a point to show insight into Leon's character.
- Adaptation Expansion: Unlike in Prehistoric Earth, where the characters' pasts before working at the park were largely kept vague, here readers learn about Drew, Leon, and Adrian's pasts in high school prior to their work at the park.
- Always Someone Better: It is revealed that, despite feeling Undying Loyalty to Drew, Leon also at times feels rather envious over how he often seems to be considered second fiddle to Drew as well. For that matter, Cass Cheng also occasionally feels this way in regards to her older sister Tina due to their parents viewing her as The Unfavorite while openly supporting Tina and encouraging the divide between them.
- Campfire Character Exploration: One of these unfolds in which Drew, Leon, and Adrian reminisce over how they were before they met and befriended each other (and Leon privately thinks to himself over some of his own personal stresses and angst) before going to sleep for their first full night in the past.
- Canon Foreigner: Not only does this episode feature the rescue of yet more speculative animals, but also the introduction of keepers Cassandra "Cass" Cheng and Mohinder Chandra, both of whom never appeared in Prehistoric Earth prior to this story.
- Curb-Stomp Battle: Much like in the previous mission, a pair of Ornitholestes (these ones of a fictional secondary European species) end up forced to give up their kill by a pack of larger carnivores. In this case, the larger carnivores are Aviatyrannis.
- Fantastic Fauna Counterpart: Played with in the back at the park scenes, in which it is revealed the majority of the keepers in the sauropod keeper division were hired from the ranks of keepers who'd previously had appropriate levels of experience working with elephants (which are arguably the closest living creature that the sauropods have to a modern day counterpart by virtue of their size and strength). Meanwhile, in the Jurassic period itself, a newly discovered in universe species of pterosaur is introduced playing a roll similar to that of plovers.
- Gentle Giant Sauropod: Just like in Novum Initium, a decent number of these appear in this mission. Doesn't stop them from putting up a reasonable fight against a pair of torvosaurus though.
- Ironic Name: Much like his namesake, Shorty the Brachiosaurus is destined to be immensely large when he's fully grown, and he's already slightly bigger than a giraffe despite still currently being a juvenile.
- Killer Rabbit: Played with in the case of the Compsognathus. They do not viciously attack and swarm anything or anyone over the course of their appearances. But nonetheless, Leon does warn Adrian and Drew to be careful nonetheless, as they could have a painful bite.
- Know When to Fold 'Em: Much like in the previous mission, two groups of carnivores pull this off. First a pair of European Ornitholestes give up their kill when a pack of Aviatyrannis call their bluff and prove to have the advantage in size and numbers. And then a pair of Torvosaurus are forced to back off after a herd of Lusotitan they try to hunt put up sufficient resistance.
- Mighty Roar: Once again averted with the giant carnivores.
- Never Smile at a Crocodile: Yet again like in the previous mission, several speculative species of small terrestrial crocodile encountered this mission prove an annoyance to capture.
- Only Sane Man: Mohinder Chandra appears to be this amongst the sauropod keepers at Prehistoric Park, to the point that he's been appointed as peacemaker amongst the division due to how the majority of his colleagues in that division appear to have severely inflated egos and a tendency to clash amongst each other.
- Raptor Attack: Just like the species more widely known and recognized in real life featured in Novum Initium, the speculative European species of Ornitholestes in this mission averts this trope.
- Reasonable Authority Figure: Both Gideon the stegosaurus and the matriarch of the larger stegosaurus herd prove to be this. As they silently make clear to each other in a glance at each other, they are both willing to respect each other's territories and boundaries as long as they stick to their respective areas.
- Shout-Out:
- The lone male juvenile Apatosaurus rescued from quicksand back in Novum Initium is revealed to have since been named Arlo. Similarly, the elderly female leader of the brachiosaurus herd is named Baylene and one of the juvenile brachiosaurus is named Shorty.
- During their first encounter with Compsognathus, Drew and Adrian make comments that are almost exact word for word quotes from a similar scene in The Lost World: Jurassic Park.
- Furthermore, this entire episode is designed to serve as an extended nod to a Dinosaur Revolution episode, complete with the presence of a male allosaurus europaeus who suffers from a broken jaw, and is subsequently named for said jaw.
- Social Ornithopod: A herd of European dryosaurus are seen peacefully feeding alongside a herd of dacentrurus. Likewise, there are herds of draconyx and eousdryosaurus present alongside a group of miragaia, dracopelta, and various sauropods.
- Stealthy Colossus: Much like the allosaurus fragilis and saurophaganax in the previous mission, the torvosaurus pair manage to successfully avoid detection by their intended prey and the rescue team until they are already within one or two feet from lunging out of the nearby foliage.
- Tough Armored Dinosaur: Amongst the animals rescued are the lesser known stegosaurs dacentrurus and miragaia and equally lesser known ankylosaur dracopelta. A very small amount of emphasis is placed on the shoulder spikes present on the stegosaurs.
