Primeval: New World is a spin-off of the British series Primeval. As with Primeval, the premise of Primeval: New World involves a team of scientists who have to deal with animals from the past and future that travel through time to the present day through anomalies, fictional phenomena which act as portals through time. Katie Newman of Impossible Pictures stated the tone of the series will be "older, darker and scarier" than the original. Connor Temple returns, and Evan faces his moment of truth against the Albertosaurus that killed his wife. When Toby is stung by a poisonous Brontoscorpio, Evan and Dylan must chase the creature back through the Anomaly to get a sample of its venom. But can they get back in time? While Dylan and Mac hunt for information on the government's secret lab, Evan goes up against Colonel Henderson Hall, who wants full access to the Anomalies. Evan and Dylan are shocked to find that Leggy, a baby terror bird, is now grown and dangerous… and has escaped from a secret government laboratory. When footage of a Triceratops goes viral, Evan and Dylan track the creature to an upscale neighbourhood, and the home of Evan's old rival, Howard Kanan.
