Purrolyth

The Pyrrolyth is a yet unseen hybrid species. It will appear in Daniel J. Cooper's time on Isla Sorna

Unlike the Indominus and Indoraptor. And much like the Scorpius Rex, the Purrolyth was born wanting to kill other creatures for fun.

The Scorpius and Purrolyth are less intelligent than Tyrannosaurus Rex. They simply don't understand the permanency of killing. Thus why they take so much pleasure in doing so, they feel no empathy for other creatures whatsoever.
