Common name: Siamotyrannus
Species: Siamotyrannus rex
Time: Early Cretaceous
Diet: Carnivore
Temperament: Blood-thirsty
Wild: At first, I thought that Charcharodontosaurus was the biggest meat-eater on the ARKs. That was before I came across the Siamotyrannus. Nearly twice the size of a Titanosaur, the Siamotyrannus is probably the largest animal on Extinction, other than some of the Titans.
The Siamotyrannus uses its great power to feed on Carchars and Titanosaurs smaller Titans regularly.
Domesticated: The Siamotyrannus can only be tamed by striking or shooting at its skull with a Mega MEK.
The Siamotyrannus makes an excellent war beast. It uses a blast of sonic energy when roaring, causing small creatures to die and even TEK structures to shatter.
