"A crocodile-dog like creature,6 meters long, scaly armor, elongated snout."

―Description

Postosuchus was a land living crocodilian that lived in North America and was the top predator in its ecosystem.

In PrimevalEdit

A Postosuchus seemingly comes through an anomaly to a South African Safari Park and kills an Eustreptospondylus (however, it is later revealed that both creatures were captured and transported the park by Tom Samuels' people). It later kills several zebra and wildebeest. The creature is later lured by an impala and attacks the team before Sophie sacrifices her life to save Danny. The creature is killed when it is shot in its stomach. Several postosuchus are used for patrolling Samuels' oil refinery as "guard dogs" and are controlled with an electric shock collar. A postosuchus later kills park worker Ted as well as Samuels. A family of Postosuchus are later seen attempting to escape their cage. It is unknown if the family survive the oil refinery's destruction although the cage may have protected them. Like the Gorgonopsid, they had tremendous power; therefore they would have caused havoc between herds of creatures in their own time. (Fire and Water).
