Ranging from eight to twelve feet tall, Phorusrhacidae Rapidesultor is a highly aggressive avian that is just barely capable of very brief "flight". Instead, it uses its wings primarily for balance during its high speed sprints. Phorusrhacidae flight is actually closer to an impressive sustained leap or glide that is assisted and lengthened by flapping of its wings.
Phorusrhacidae shows interesting traits related to theropods such as Utahraptor, Carnotaurus, and Tyrannosaurus. It has many similar traits, such as general shape and predation patterns, but its attacks tend towards lightning dashes and leaping slashes.
Phorusrhacidae is an excellent combat mount, particularly for harassing and scouting. Riders of Phorusrhacidae gain most of the benefits of a fast, mobile ground-based theropod, while also gaining some of the freedom of movement of a flyer... assuming the rider can coax Phorusrhacidae into staying in the air over a long leap.
— The Dossier
The Phorusrhacidae or Terror Bird is a small carnivorous bird found on the Ark.
- The skull that is seen in its dossier appears to be of the famous terror bird Phorusrhacos.
- The dossier image of the Terror Bird shows it with a vestigial dew claw, but the in-game model of the creature lacks this feature.
- Despite spawning most commonly in the mountains, real life Terror Birds were plains dwellers that hunted out in the open.
