Concavenator

Known as the “hump-backed hunter from Cuenca” Concavenators existed during the early Cretaceous era in Las Hoyas, Cuenca Province, Spain. They belonged to the family Carcharodontosauridae and were known to be medium sized carnivorous theropods that grew to be an estimated 20 feet long with an average weight between 1 and 2 tons.

Behavior

Concavenators are medium-sized theropod dinosaurs that grow to be around six meters in length and are most famous for their distinctive hump or ridge on their back, formed by elongated vertebrae in front of their hips. This feature’s purpose remains uncertain, though scientists suggest it may be used for display, fat storage, or thermoregulation. Concavenator lives in warm, humid, wetland environments filled with lagoons, forests, and abundant wildlife. It is a carnivore that preys on small to medium herbivorous dinosaurs, reptiles, and fish, using speed, stealth, and strong arms with clawed hands to capture prey. Concavenators are often presumed to be most active during the early morning and early evening hours.

Mandatory TRaits

Ambush Hunter

Concavenator groups consisting of 4+ will spread themselves out in dense vegetation, riverbanks, and heavily forested areas and patiently wait for prey to migrate through their trap. Once prey is within the ambush zone each Concavenator on the team can strike the prey, trading off with their fellow Concavenators to avoid biting each other. The size of the Concavenator group will determine the prey they can perform an ambush tactic on. Those group size requirements are as follows:
4 Concavenators = Tier 4 or less. 6 Concavenators = Tier 5. 8 Concavenators = Tier 6.

Murder Party

Concavenator groups with less than 4 members if in LOS of any dinosaur that is visibly bleeding may assist in the take down of that dinosaur (third party allowed). However, the Concavenators must eat last unless they decide to contest the body down, which can only be done if each Concavenator’s health is over 50%.

King of the POI

Concavenator groups of 4+ will always lay claim to the POI they are currently in. If an opposing Concavenator group arrives in the POI the presiding group shall aggressively call the group away. Should the group not disperse both Concavenator groups will fight to the death. The victor owns that POI for the next 4 seasons. No other concavenators shall pass through unless part of the winning Concavenators group, or alone and accepted into the group by the victor. Lone Concavenators looking to join a group that has claimed a POI should bring a preferred diet meat to the POI King’s group or a trophy from a dinosaur they have killed.

Optional TRaits

Lone Conc

Lone Concavenators, while formidable predators, are weak on their own and will only hunt critters and Dinosaurs tiers 2 and below. Lone Concavenators should always seek to become part of a larger group so that they may thrive better than on their own. Lone Concavenators will not display bright coloring as their poor diets cannot sustain the vivid coloring produced when eating more nutritious meals. Lone Concavenators will always seek out easy meals through scavenging when and where possible.

Emperor’s Retinue

Up to two Concavenators may choose to serve as Flamekins to a Yang, acting as scouts, lookouts, and hunting assistants while remaining under the larger predator’s authority. Opportunistic by nature, Concs are quick to recognize the advantages of traveling beside a Yang. The larger predator provides protection, access to kills, and the ability to tackle prey far beyond what a Conc could reliably challenge alone. In return, the Conc serves as the Yang’s eyes and ears, warning of danger and keeping watch over the surrounding area. While scouting, a Conc must remain close enough for its Yang to hear and respond to its calls.

The Yang must be the one to initiate all hunts. Concs may assist once the hunt has begun and may not pursue prey more than four Yang body lengths away from their Yang.

In return for their service, Concs are afforded the protection of their Yang on land and are typically granted access to its kills.
Concavenators and Yangs may not court, nest, or raise offspring together.
