When does Primal return?

Primal (also known as Genndy Tartakovsky's Primal or Primal: Tales of Savagery) is an American adult animated action horror television series. It is the first combined action/sci-fi/horror animated series from Cartoon Network Studios and Williams Street. Set in an anachronistic vision of prehistory, portraying extinct dinosaurs, Ice Age mammals, early hominids, and post-metallurgy Homo sapiens all coexisting in a single time period. The first two seasons revolve around the journey of Spear (Aaron LaPlante), a Neanderthal, and Fang (Joel Valentine), a uniquely intelligent female Tyrannosaurus rex.
Set in an anachronistic and fantastical prehistoric world, the series is about the survival and bond between a Neanderthal man and a female Tyrannosaurus rex named Fang.
