|— Allen, describing Psotosuchus|
Postosuchus (name meaning "Crocodile from Post") is a genus of rauisuchid reptile that originated during the Late Triassic period in what is now North America. Measuring 6 meters long and weighing around a ton, Postosuchus was the apex and largest predator of its day.
In the Series 2 premiere "Birth of the New Blood", a pair of Postosuchus were brought back to the park from Late Triassic Arizona, 225 million years ago.
Era & DiscoveryEdit
Postosuchus lived during the Late Triassic Period 225-208 million years ago and was the apex predator of its time. It was first discovered in 1980.
Postosuchus was the largest predator on the Earth during its time. Measuring up to 20 feet (6 m) in length, standing more than 6 feet (2 m) tall on all four legs, weighing 1-2 tons (2,000-4,000 lbs.), and heavily built with an armored back, these predators needed a large amount of food and water. Therefore, they had to defend an enormous territory. While rearing up on their hinds legs for a few moments, Postosuchus stood around 10 feet (3 m) tall.
Postosuchus was a distant relative of the dinosaurs, having evolved from the same reptilian ancestors. However, unlike the dinosaurs, Postosuchus was too front-heavy to run on two legs, yet they were easily fast enough to keep pace with a herd of Placerias.
Behavior & TraitsEdit
A ruthless ambush predator, Postosuchus was a solitary creature, only getting together with others of its kind either during mating season or during confrontations. Additionally, both males and females were very territorial of each other.
Much like Tyrannosaurus rex, the only creatures on the planet Postosuchus feared was their own kind. Additionally, similar to modern bears, Postosuchus was able to rear up on their hind legs, or at the very least for a few seconds, stood on their back legs to scare off other creatures, even their own kind.
- The sound effects of Postosuchus are a mix of crocodilian hisses, large cat growls, and bear roars.
- It is now theorized that Postosuchus may have been a bipedal walking reptile, at least some time.
- Postosuchus was one of the last of its kind, with the last of the rauisuchians becoming extinct at the end of the Triassic period. It was also one of the largest of its kind.
